The Solar System According to Mrs. Tateâ€™s Class
THE SUN by Miles
Did you know 1 million planet earths can fit in the sun? The sun is about 27 million degrees Fahrenheit. Anything you throw into the sun will turn in to gas. The sun is the closest star to earth. The sun helps planets grow so animals can eat. The sun also gives earth power. The sun gives light and heat to the earth. The Sunâ€™s gravity holds the gases of the Sun together in a ball. The Sun is the biggest star in the universe. It is a lot of fun to study space. I thought I knew a lot about the Sun but now I realize there was lots more to learn.
The Sun By Akasha The sun consists of hot plasma. It is actually 5 billion years old. There is no gravity on the sun. If you lived there you would die. If you stared at the sun too long, your eyes would get injured . The sun is made out of gas. If we did not have the sun, we would not be here on Earth. The sun is 865,000 miles in diameter. Imagine if the sun were a soccer ball and the Earth was a pea and you would have a comparison of the size of the Sun compared to Earth. The sun’s black spots are actually cool spots. People usually call them sunspots. Our sun can fit over 1000 earths in it. Our sun’s core is about 27 million degrees Fahrenheit. We can see the sun in the daytime. Every planet in the solar system rotates around the sun. The sun has a magnetic field just like mercury. Solar flares are very huge explosions. The coolest part of the sun is nearly 10,000 degrees Fahrenheit. The sun could swallow up Mercury, Venus, Earth, and Mars. The Sun has no water inside it. Our sun has 5 billion years more to shine for us. Our sun shines every day for us and shines on the moon every night. It is a good thing we do not live on the sun or we’d be toast!
The Sun by Dazzling The sun is a star. It is the biggest star in the sky. The sun is a ball of gas.
We canâ€™t live on the sun. It has gravity. The sun is really hot. Did you know it would take one hundred earths to fill in the sun?
Mercury By Aaron
Mercury is the planet that is closest to the sun. The sun appears two and a half times larger in Mercury’s sky compared to Earth’s. It is visible in the morning and evening and it’s called a morning star or an evening star. It is interesting to know that it is made mostly or iron and has a very thin crust. Its crust is 100300 kilometers thick while the mantle is 600 kilometers thick and its core has a radius of 1800 kilometers. Mercury’s crust is so hard that the molten core can’t go through it! Mercury has a diameter of 4,879.4 kilometers. This planet has craters from asteroid and comets that hit its surface. It also has a little helium and hydrogen in its atmosphere. It has a magnetic field that holds objects in its atmosphere. Mercury has a high temperature of 800 degrees Fahrenheit and at night it gets as cold as 300 degrees below zero Fahrenheit. Mercury doesn’t go in a perfect circle when it goes around the sun. It does not have a moon. Half of it has not been seen! One day on mercury is equal to fifty eight and a half Earth days. A year on Mercury is eighty eight Earth days.
Mercury is 36 million miles away from the sun. It is 57 million miles from Earth. It is interesting to know that if you weigh 100 pounds on Earth, you would weigh 38 pounds on Mercury. It actually is a little bit bigger than our moon. I was so excited to be doing research on space that I created both a Power Point and a report on the subject. One of the things that is cool about being a third grader is that I was able to do this all by myself!
Venus By Liam
Venus is the second planet from the sun. Venus has been thought of as Earthâ€™s twin. Both planets are about the same size. The planets have a close orbit. Venus is named after the Roman God of Love and Beauty. It is one of two planets that does not have a moon. Venus has been orbiting for hundreds and thousands of years. The Mayans thought the Sun and Venus protected the Earth at night. They thought it was the Sun and Venus because they rose and set at the same time. Venus has deadly acid clouds and is very hot. If you weigh 70 pounds on earth, you would weigh 63 pounds on Venus. Venus has been one of the most misunderstood of all the planets in our Solar System. Venus rotates in the opposite direction of almost all of the planets in our solar system. There is still a lot about the planet that we donâ€™t know. We do know that the pressure of the air on Venus is 100 times greater than on earth. The wind on Venus blows three times faster than a hurricane. There are volcanoes and lightning on Venus. Venus does not have a magnetic field so a compass would not work there. Venus has been explored by seventeen spaceships. That is amazing. In the coming years, I bet lots more will be learned about Venus!
Venus By Gaje Before the first telescope was invented, astronomerâ€™s observed stars in the sky. They noticed that some of these stars seemed to be traveling among others. Venus is the second planet from the sun. Venus is one of four inner planets that have rocky surfaces. Venus has a poisonous atmosphere. Venus has 400 degree hot gasses and iron. Venus has no life on it.

Venus is covered by yellowish clouds. Venus is the brightest planet in the solar system. It is the sixth largest planet in the solar system.
Venus is a planet that only stays hot. Venus has no moons and is a rocky planet. Venus is a small planet. It is named after Aphrodite, a Greek goddess. Venus is the first planet to be visited by a space craft. Venus is the planet that has the largest volcano in the solar system. Venus has volcanic rocks on its surface. Venus rotates in the opposite direction of earth. I liked learning about Venusâ€™ special facts. It is http://upload.wikimedia.org/wikipedia/comm ons/thumb/8/85/Venus_globe.jpg/220pxVenus_globe.jpg
hard to believe that it is so far away but we can see it in the sky.
This is known as Venus. http://upload.wikimedia.org/wikipedia/commons/thumb/8/83/Pink_Venus_symbol.svg/400px-Pink_Venus_symbol.svg.png
by Ethan P
Earth is the 3rd planet from the sun. Its orbit takes about 365 days or a year. The planet is 92,960,000 miles from the sun. Earth’s symbol is a circle with a + in it. The average temperature is 59 degrees F, or 15 degrees Celsius. The earth is made out of many different materials. It is made of layers. The layers are: the Atmosphere (and in it there is the exosphere, thermosphere, mesosphere, stratosphere and the troposphere), Crust, (upper mantle, mantle), Outer Core and Inner Core. Earth’s atmosphere is a layer of gases that surrounds the planet. Earth’s atmosphere does not float off into space because it is held together by Earth’s gravity. The atmosphere protects earth from meteoroids, comets, asteroids and other space junk also making it possible for life. The
http://static.howstuffworks.com/gif/asteroid-hits-earth-2.jpg atmosphere is made of chemicals. Life is also possible on Earth because of its distance from the sun which makes it the right
temperature for life and the right environment for life. Earthâ€™s orbit around the sun is not a perfect circle; it can vary. The time it takes for Earth to orbit the sun is called a year. It takes 24 hours for Earth to orbit on its axis. Twenty four hours on Earth is a day. What I enjoyed most about reporting on Earth is the typing the document about it. I also liked researching about it. I found it to be a good experience.
Mars By: Danny
Mars has 2 names: Mars, and the red planet. Mars has 2 polar caps that get thicker in the winter. There might have been huge oceans on Mars. There is a canyon that is as large as the distance of New York to San Francisco. There are volcanos on Mars. There is a volcano that is 17 miles high named Olympus Mons. There are dust storms that can cover the whole planet. They are called dust devils. Mars has glaciers like Earth. Mars is the 4th planet from the sun. There is Mercury, Venus ,Earth and Mars. These make up the 4 inner planets. Marâ€™s orbit is slower than Earthâ€™s. All the inner planets are made of rock. Mars is mostly rock and ice. There are clouds on Mars like on Earth. Mars was named after the Roman God of War. If you weigh 70 pounds on Earth, you would weigh around 27 pounds on Mars. Scientists think there where huge floods on Mars the, biggest in the solar system. Mars has a big red spot; it is a big storm. Mars has some huge craters; there is one that is 2 miles wide!
Marâ€™s tectonic plates are vertical, not horizontal like Earthâ€™s. Scientists think Mars has clues about life on Mars now or long ago. Mars is too cold for water to exist and the atmosphere is too thin for water to exist for a long time. There might still be water under the surface. Mars has two moons, Phobos and Deimos. Phobos is the larger of the two. Scientists think Phobos will crash into Mars in the next 5 billion years. People think they are asteroids that Mars caught with its gravity. A day on Mars is 24 hours 39 min. 35 seconds. It takes 687 days for Mars to orbit the sun. Mars has a tilted axis. It has seasons. There are 80 mile per hour winds on Mars. Rovers found river beds on Mars. In 1977, Mariner 9 went to Mars and discovered Olympus Mons and it made pictures of huge canyons. In 1975, two rockets landed there to study its surface. In 1997 the Mars global surveyor made a map of Mars. As you see, Mars is a very interesting planet to study .I was particularly fascinated to think about the possibility of life Mars.
Jupiter by Kaleigh Jupiter is the biggest planet in the solar system. You can fit 100 Earths in Jupiter’s Red Spot. Jupiter is twice the size as the other planets in the solar system. Jupiter has rings like Saturn and Uranus. Jupiter has three rings in total. Jupiter is 983 million miles from the sun. Jupiter’s temperature rises to 30,000 degrees Celsius. Jupiter is known to be a gas giant. Jupiter’s radiation is so strong it can be detected on Earth. The clouds around Jupiter move at about 100 miles per hour. Jupiter was named after the Roman god of the heavens and weather. Jupiter has about 50 moons. Astronomers have seen 34 moons around Jupiter. Jupiter spins faster than any other planet in the solar system. Jupiter spins so fast that the days are ten hours long. It takes twelve Earth years for Jupiter to finish a spin around the Sun! There is more than two times as much gravity on Jupiter as on Earth. If you weigh 100 pounds on Earth on Jupiter you will weigh 264 pounds. The most interesting part about learning about Jupiter is reading about Jupiter’s red spots. I thought that studying Jupiter was really fun because I learned so much. I think it might be a bad place to live because it is really cold and strong winds.
Europa By Emma I’m very excited to tell you all about Europa, one of Jupiter’s moons. It’s one of the four of Jupiter’s moons. If you read this information you may learn something new! Europa is one of Jupiter’s moons. Europa is a bit smaller then earth’s moon. Like Earth, Europa has an iron core. Europa has a rocky mantle and an ocean surface of salty water. But unlike Earth, this ocean is deep enough to cover all of Europa. Because it is so far from the sun, the ocean is frozen. This frozen surface may be only a few kilometers thick. Europa has a layer of water around 62 to 63 miles deep. Europa orbits Jupiter every 3.5 days. Just like earth’s moon, the same side of Europa is always facing Jupiter. Europa was found on the 8th of January, 1610, by someone named Galileo Galilee. Europa has its own atmosphere. Even now, it is very thin. Since Europa has its very own atmosphere with molecules that can escape, there’s a donut like shaped belt of materials inside Jupiter that’s called Europa Tores. Europa’s surface is one of the lightest and brightest in the solar system. Europa is only one of Jupiter’s moons. There is also Lo, Calisto, and Ganymede.
I think what I found most interesting about this report is just learning all this new information about the solar system. As for Europa, I never knew that other planets had moons.
by Emma K
Saturn is the 6th planet from the sun. It’s the second largest planet in our solar system. Saturn is in the outer solar system. Saturn is made up of materials which are ice, gas and liquids that are even lighter than water. If there was an ocean big enough to fit Saturn in it, it would float on the water. Saturn is a giant ball of gas. Saturn’s atmosphere is 285 degrees Fahrenheit hot. Saturn’s core is so hot that it’s even hotter than the sun. It’s funny because the sun is in the inner solar system and Saturn is in the outer solar system. Maybe it gets its gas from the Sun. Saturn’s atmosphere is made out of helium and hydrogen, just like the sun! Saturn orbits in an oval shape. It takes Saturn 10,747 days to orbit around the sun. Saturn does not cut into any other planets’ orbit. Saturn has at least 60 known moons. While Saturn is orbiting around the sun, Saturn’s rings are circling around Saturn. Saturn rings are made of tiny pieces of rocks and dust. Saturn’s rings are the brightest and have the most rings in the universe. Saturn’s rings are so thin you have to use a telescope to see them. Saturn’s rings are held together by Saturn’s gravity when it pushes and pulls. Titan, one of Saturn’s moons is larger than Mercury. A 100 pound object on Earth would weigh 116 pounds on Saturn. Saturn has the lowest density of all the planets in our whole solar system. Saturn does not have a solid surface. Titan is the only Saturn moon with an atmosphere. Saturn is a very interesting planet to study. It is probably the easiest for us to identify because of its rings. It was fun to do this report by myself.
Saturn By Jack Saturn is among one of the weirdest planets in our galaxy. Saturn is the 6th planet from the sun and the 2nd largest planet, Jupiter is the largest. Only 3 space probes explored Saturn. There are about 8 moons orbiting Saturn, probably more. One of Saturnâ€™s moons is the 2 largest moon in the galaxy. Saturn is made mostly of methane gas. Its fire-like core is made of other gases. One of Saturnâ€™s moons is really close to supporting human life. It has as much air needed to have humans living there. We could not live on Titan. It is just too cold. I mean like Antarctica cold only colder. nd
Saturn has another moon that looks like an asteroid. It is the ugliest moon in the Galaxy. The 2nd ugliest moon also orbits Saturn. Its crater is huge. The 3rd ugliest moon has craters all over it. It also orbits Saturn. Saturn has 3 space probes orbiting it, Pioneer 11 and the Voyager 1 and 2. NASA workers think they will be working until 2015!!! Saturn is one of my favorite planets. It probably has the best collection of rings in the Solar System. I really enjoyed learning about it.
URANUS By Rory
Uranus is the seventh of eight planets from the sun before Neptune. Uranus has a blue green color. It was named after the Roman and Greek God of the Sky. Uranus is the third biggest planet and the fourth biggest in mass. Mass means weight. Uranus’ mass is 14.5 times as that of Earth. Uranus is much, much larger than all the land planets. The land planets are Venus, Mars, Earth, and Mercury. Pluto could be a land planet because it is bigger than Mercury. Pluto is now a dwarf planet. The rings of Uranus were first seen after Saturn’s rings. There are 13 known rings around Uranus. There are two sets of rings, an outer and an inner. Uranus’s inner rings are like Jupiter’s rings because the rings are dark. The outer rings are lighter colors. One is red and one is blue. Uranus has 27 moons that are known. Oberon and Titania are the biggest moons of Uranus. Those two moons were also the first to be discovered. They were discovered by William Herschel in 1787. Herschel was a British astronomer and he discovered Uranus and those two moons. William Lassell discovered the next two moons in 1851. William Lassell is also an English astronomer. In 1986, Voyager 2 went to the Uranus system and discovered 10 more. The Voyager 2 is a special spacecraft that visited the outer gas giant (a giant ball of gas like Jupiter and Saturn and Uranus and Neptune – the outer planets) because the astronomers wanted to learn more about the outer planets. Uranus is on its side. It is practically pointed to the sun. The rings go from top to bottom. It is tilted that way because something hit the planet with such a force that the planet stays like that. Uranus is going around the sun on its side. The atmosphere of Uranus is made up of mostly hydrogen and helium gases. The core is made up of rock. Even though the core is made out of rock, the core is not solid. Uranus is the coldest planet. It is also known as the ice planet. When winds blow around the planet rapidly, it makes it the coldest planet. It takes 84 Earth years for Uranus to go around the sun. It takes about 30,681 to go around the sun!!! It takes 17.24 hours for Uranus to rotate on its axis. That is one day on Uranus. That is much shorter than Earth days but Uranus takes longer to orbit the sun.
I chose to study Uranus because my mom studied Uranus. She had to write a report on Uranus, too. She accidentally wrote about the god instead of the planet, and had to do the report twice! My favorite part of learning about this planet is that I got to learn why it is the coldest planet. I also thought it was cool that an aircraft went to Uranus and all the other gas giants. It was called the Voyager 2. I also liked that it was the first planet to be discovered in modern times with a telescope.
Neptune By Rayna
http://jewelryandgemsforselfdiscovery.com/blo g/wp-content/uploads/2011/03/Neptunedreamstime_7902044.jpg http://www.horoscoper.net/images/jpg/Neptu ne.jpg
Neptune is the farthest planet from the sun. Neptune has the wildest weather in the solar system. The winds blow 1,200 miles an hour. Neptune does not have an outer crust. It has a cold and a gassy surface. Neptune has 4 rings. Neptune is named after the Roman God of the Sea. Most planets are named after Roman gods. If you think hurricanes are bad, check out Neptune! It has the worst hurricane in the solar system. Neptune has 8 moons. The biggest moon is Triton. Neptuneâ€™s moons were discovered on October10th, 1846. Neptune is made out of hydrogen, helium and methane gas. Neptune has a rocky core that is hotter than the sun! Neptune orbits around the sun every 165 years. It orbits very slowly. Neptune has a great dark blue spot on it. Unlike Jupiter which has a great red spot, Neptuneâ€™s spot is a hurricane. I enjoyed studying about Neptune because I learned things I did not know. For example, I did not know that Neptune was named after the Roman God of the Sea.
Neptune by Holly Neptune is a gas giant. It is made of mostly gas, rocks and unknown ices. There is a giant storm which they call the Great Dark Spot that has seemed to have disappeared. Scientists are now not even sure that it exists. Neptune’s winds blow at 2,000 kilometers an hour. Neptune has eight moons, Triton, Thalassa, Naiad, Despina, Galatea, Larrissa, Proteus, and Neried. Triton is one of the coldest places in the solar system. Neptune has a system of rings; scientists are trying to learn what they are made up of. All they know so far is there are only four rings altogether. Neptune is named after the Roman God of the Sea. It is blue because of the methane gas in its atmosphere. They named the planet after the Roman God of the Sea because of its blue color. Neptune has a thin atmosphere made out of mostly clouds. There is one huge cloud that scientists call “The Scooter” because of its scooting motion. Neptune has a rocky core and no real surface. Neptune’s core is hotter than the sun. Neptune is the eighth planet from the sun. It takes Neptune 165 years to orbit the sun. Neptune is a little smaller than Uranus but a little heavier. It is much larger than Earth and is the farthest planet from the sun.
Not all planets have a nickname but Neptune does. Most people call Neptune “The Blue Planet.” In the olden days, telescopes weren’t strong enough to see Neptune. It was discovered because Neptune’s gravitational pull affected Uranus.
Neptune is the windiest place in the solar system. The winds on Neptune are six times faster than any winds ever recorded on earth. Neptune’s magnetic field is 27 times more powerful than earth’s.
I enjoyed learning about Neptune because it is a very interesting planet and has lots of special features. My favorite fact that I learned was that Neptune is the windiest place in the solar system. I really enjoyed learning about Neptune and I hope you did to.
Neptune By Jordan Neptune is the 8th planet from the Sun. Neptune is 2.8 million miles away from the Sun. Light from the Sun takes about 4 hours to reach Neptune because it’s so far away. Neptune and all the other gas giants are made up of mostly hydrogen, helium and methane gases. The methane gases that are on Neptune make Neptune blue. This is because the gas absorbs the red light and reflects the blue back into space. The great dark spot on Neptune is, like the great red spot on Jupiter, a storm. The white clouds on Neptune are methane ice crystals. One time out of 165 years on Earth, Neptune orbits the Sun. Right now, Neptune will not finish its orbit till 2014. One time about every 200 years, a planet called Pluto will come inside Neptune’s orbit. Like all the other planets, Neptune has an axis. An axis is an invisible line that goes through the center of a planet. Once every 16 hours and 7 minutes Neptune spins on its axis. Triton was the first of Neptune’s moons to be discovered. Triton is Neptune’s largest moon with a diameter of 2700. Triton is the 7th largest moon in the solar system. Triton’s crust is made of frozen nitrogen. This is a chemical element that covers an icy mantle. People believe that Triton’s core is made of rock and metal. Neptune is named after the Roman God of the Sea, Neptune. Neptune always carried his Triton with him. That’s why Neptune’s moon was named Triton. All the planets were given symbols; this is Neptune’s. Neptune has 6 rings. Neptune’s rings have places that are thicker than other places. Neptune was visited by Voyager 2 in 1989. Until Voyager 2 came to Neptune, it was thought that Neptune’s rings were arches.
You can weigh more on Neptune than you do on Earth. For example, if you weigh 70 pounds on Earth, then you weigh 78.5 pounds on Neptune. Neptune can fit about 42 Earths. Neptune has the strongest winds of anywhere in the solar system with 400 miles per hour up to 1,500 per hour. I enjoyed learning about Neptune because it was fun to become an expert on a planet that at first I didn’t know much about. The fact I thought was most interesting was “Before Voyager 2 came to Neptune it was thought that Neptune’s rings were arches.” I hope that you will think that Neptune is as interesting as I think it is.

PLUTO by JACOB
Pluto is the 9th planet from the Sun. That makes it the farthest planet from the Sun. It is 2.7 billion miles from the Sun. Clyde Tombaugh found Pluto in 1930. He was only 24 years old when he made this discovery! Pluto was actually named after Hades by an eleven year old. Pluto is all ice and rock, and its atmosphere is methane and nitrogen. If you weigh 70 pounds on earth, you will weigh 4 pounds on Pluto! Pluto orbits around the Sun in 90,465 days. Long year!! Pluto’s rotation equals 6 days and 9 hours. Pluto has one moon, Charon. Pluto is the only planet that was named by an 11 year-old kid! Pluto’s orbital path is filled with ice and rock! Pluto’s sign has a P and an L mixed together. In 2006, a space shuttle launched for a visit to Pluto. It is still out there. I liked studying my planet because it became very special when it was declared a dwarf planet.
Kuiper Belt By Mikayla I am really excited to tell you about the Kuiper Belt because a lot of people do not know about it. The Kuiper Belt is a lot of icy objects that orbit Neptune. Pluto is the largest member of the Kuiper Belt that scientists know of so far. Some of the systemâ€™s moon, like Neptune and Saturn, are also believed to be in the Kuiper Belt region. The orbit after Pluto is called the Kuiper Belt. The sunâ€™s gravity keeps hundreds of small icy objects in the belt. The Kuiper Belt is shaped like an ellipse. http://www.solstation.com/stars/k-belt1.jpg
Eris is a dwarf planet just like Pluto. Scientists know little about the Kuiper Belt. Scientists know there are nine spheres orbiting between Jupiter and Neptune. It seems that in the Kuiper Belt there are swarms of ice objects orbiting the sun beyond Neptune. The Kuiper Belt is a ring that goes around the sun. The dwarf planets that orbit in the Kuiper Belt are Eris, Pluto, Haumea and Make Make. The Kuiper Belt is located around 2.8 billion miles from the sun or [4.5 billion km] from the sun. The Kuiper Belt is named after the astronomer Garard Kuiper. What I found most interesting was that the Kuiper Belt has dwarf planets. I also found interesting that the Kuiper Belt is 2.8 billion miles from the sun.
Makemake By Tyell
Makemake was named after an Easter lsland god. Makemake is a dwarf planet like Pluto, and Eris. Makemake was discovered in 2005 by Mike Brown. Makemake does not have a moon at all. Makemake was named as a planet three years ago. There are three more dwarf planets beside Makemake that are relatively new: Pluto, Cares and Eris. Makemake is a Kuiper Belt object. Makemake is a very icy world that orbits far away from the sun with a frozen surface. Makemake takes 310 years to go around the sun. It is smaller than Pluto and Eris. Makemake is three fourths the size of Pluto. It does not have a moon. I liked studying Makemake because it is unique and a lot of people donâ€™t know about it . I just donâ€™t like that it is so cold!!
Eris by Ethan
Eris is the coldest and largest dwarf planet in our Solar System. Some call it the deadliest planet because its temperature makes it impossible to support living things. We would freeze to death if we tried to be there. It was discovered in 2003. Eris is made of rock and ice. It has its own small moon. It takes 560 years for Eris to go around the Sun. This is because it is not a fast moving planet. The Kuiper Belt is made up of objects that are orbiting the Sun beyond Neptune. These objects form a belt around the sun. Eris is part of the Kuiper Belt. Eris is 3.6 billion miles from the sun. It has been described as the most distant object orbiting the sun. Of course, because it is so far away it is also a lot colder. I think it is cool that Eris is a â€œnewâ€? planet. Scientists keep learning more and more about our solar system. It is amazing to realize that there is so much to know about it!
Comets By Aaron A comet does not have an atmosphere because it is too small and it does not spin. If two comets come together they will go in different directions. They could also bounce into another comet. Comets come from the Kuiper Belt. They also come from the Ort cloud. Comets can be close to the sun and others can be really far away from the sun. A comet is made of ice. It is also made of dust and rock. When a comet comes to the inner solar system, it starts to burn up and possibly gets on fire. Also, it might leave a trail behind itself and that is called a tail. Comets can be hurtful. Comets are very small. When a comet is very far away from the sun, it is solid. When it is close to the sun, it is very hot and warm. When a comet is close to the sun, some of the ice is turned into gas. Rocks from planets and moons come off and make comets. I like studying these rocks because they are so interesting. One of the most interesting thing about comets was it forms a tail by itself. I also liked doing this and I got to do this all by myself.
