The Solar System The Solar System is just a small part of the Universe. It is located in the Milky Way galaxy. The Solar System consists of the Sun and everything that moves around it. This includes the planets, their satellites (or moons), asteroids, comets and other objects.
Did you know?
The layers of the Earth
Our galaxy, the Milky Way, contains more than 300 billion stars. It takes light 100 000 years to travel from one side of our galaxy to the other!
The Sun is a star and it emits light and heat. It is at the centre of the Solar System. Eight planets move around the Sun. The four inner planets are Mercury, Venus, Earth and Mars. The four outer planets areÂ Jupiter, Saturn, Uranus and Neptune.
Uranus is the second furthest planet from the Sun. It is the coldest in the Solar System.
When we see the Earth from space, we can identify its three different layers: the atmosphere, hydrosphere and geosphere. A
The atmosphere is all the air that surrounds the Earth. The air we breathe is a part of the atmosphere.
The hydrosphere is all the water found on and above the Earth. The oceans are a part of the hydrosphere.
The geosphere is the hard part of the Earth. The continents make up the geosphere.
The Sun is a medium-sized star. The light and heat it emits are essential to life on Earth.
Jupiter is the largest planet in the Solar System.
Neptune is the furthest planet from the Sun.
Mars is sometimes called the Red Planet. Saturn has rings that are made up of rock and ice.
Earth is the only planet we know that supports life.
Mercury is the smallet planet and the closest to the Sun.
In other words
Earth is also called the Blue Planet. It has this name because most of its surface is covered in water. Earth is the only planet in the Solar System with lots of liquid water on it.
Venus is the closest planet to Earth and second closest to the Sun. It is the hottest planet in the Solar System.

How the Earth moves The Sun and the seasons
The Earth moves in two ways: it rotates on its invisible axis and it revolves around the Sun. sible line Rotation: the Earth’s axis is an invi the that goes through the North Pole to axis. South Pole. The Earth rotates on its tion. It takes one day to complete one rota Earth and The Sun shines on one half of the this is why we have day and night.
The Earth’s revolution around the Sun produces the seasons. There are four seasons: spring, summer, autumn and winter. Each season is three months long.
NORTH POLE NO
In autumn, the days and the nights are more or less the same length. In Spain, autumn starts on 21 September.
It’s day on the half of the Earth that faces the Sun. SOUTH POLE
is Revolution: the second movement . the Earth’s revolution around the Sun One complete revolution takes 365 is days and six hours (one year). This res, why we have different temperatu weather and seasons.
In summer, the days are longer than the nights. We receive more light and heat from the Sun. In Spain, summer starts on 21 June.
It’s night on the half of the Earth that faces away from the Sun.
In spring, the days and the nights are more or less the same length. In Spain, spring starts on 21 March.
In winter, the days are shorter than the nights. We receive less sunlight and it’s colder. In Spain, winter starts on 21 December.
Dividing up a year It takes the Earth one year to revolve around the Sun. We divide years into months, weeks, days, hours and minutes. Year

How the Moon moves
The Moon is the Earth’s only natural satellite. The Moon takes 28 days to revolve around the Earth. Like the Earth, the Moon rotates on its axis. It also takes 28 days to do this. From Earth we see the bright side of the Moon. This side is illuminated because it reflects sunlight.
In the four boxes we see the Moon as we see it from Earth. third quarter
Does the Moon change shape? The Moon sometimes looks like changes shape. We call these shapes the phases of the Moon. There are four main moon phases: new moon, first quarter, full moon and third quarter.
Cardinal points To know where we are on the Earth or to tell someone how to get somewhere, we need to know how to give directions. To give directions, we use the cardinal points: north, south, east and west. On maps, we see the cardinal points as letters: N, S, E and W.
To know where north is, we use a compass. Compasses have a magnetic needle that always points north.
Sunrise and sunset full moon
The Sun rises in the east and sets in the west. This is because the Earth rotates from the west towards the east.
Did you know?
The first compasses were invented in China around 1800 years ago. They were made using a natural magnet called loadstone. They weren’t used for orientation, but to help people make decicions.

1 Read and discover. Life on Earth would not exist without the Sun. The Sun is our main source of light and heat. It is also the most important factor in producing weather. The Sun is a very active star. During periods of high activity, the Sun emits huge amounts of energy in solar storms. These explosions can damage satellites orbiting the Earth and even produce power cuts in our homes. Solar storms also create the auroras.
2 Why is the Sun important? 3 What are solar storms? 4 Sunlight is one of the conditions necessary in the process of photosynthesis. During this process, plants produce chemical energy. What do you think would happen to life on Earth if plants didn’t receive sunlight? 5 What might happen if satellites orbiting the Earth were damaged? Consider the consequences of damage to the different types of satellites:
• weather satellites • navigation satellites • communications satellites 6 There are two types of aurora: aurora borealis and aurora australis. What is the main difference between them?

The Universe includes planets, stars, solar systems and galaxies. No one knows exactly how big the Universe is. There are many theories about how the Universe was formed. Most scientists think that the Universe was the result of a giant explosion called the Big Bang. After the Big Bang, the matter in the Universe started to group together forming the different celestial bodies.
What is bigger: a star or a galaxy?
Planets and dwarf planets are celestial bodies that orbit a star and do not emit light. Some planets have satellites in their orbit, which do not emit light either. Pluto is classified as a dwarf planet.
A comet is made of ice, dust and gases. Comets come from areas of the Solar System beyond Neptune and orbit the Sun in elongated ellipses. A comet has a nucleus, a coma and a bright tail which always points away from the Sun. The coma and the tail form as the Sun melts the nucleus.
Stars are huge spheres of gas where nuclear reactions take place. These reactions produce enormous amounts of light and heat. Stars are classified by three characteristics: colour, luminosity and size. A constellation is a group of stars which make an imaginary shape in the night sky. Some constellations, such as the Great Bear, are named according to their shape. A galaxy is an enormous system of stars, dust and gas that is held together by the force of gravity. Galaxies can have different shapes: spiral, elliptical or irregular. There are billions of galaxies in the Universe. Our solar system is one tiny part of a spiral galaxy called the Milky Way. All galaxies are constantly moving through space.
Other celestial bodies
A spiral galaxy
Galaxies group together forming bigger structures called galaxy clusters. A galaxy cluster consists of hundreds or even thousands of galaxies.
Meteoroids are small pieces of rock or metal from an asteroid or comet that orbit the Sun. When a meteoroid passes through the Earthâ€™s atmosphere, it burns. This burning rock is a meteor, also called a shooting star. At certain times of the year we can see meteor showers. The pieces of meteor which hit the Earthâ€™s surface are called meteorites.
An asteroid is a rocky, irregular mass that orbits the Sun. Some asteroids are the size of small stones, but others can be bigger than a dwarf planet. Most asteroids take three to six years to orbit the Sun.

a. An asteroid is made of ice, dust and gases and has a bright tail pointing away from the Sun. b. We classify stars according to their shape. c. Planets and dwarf planets do not emit their own light. d. Some stars can also be shooting stars.
The Solar System
The Solar System is located at the edge of the Milky Way. It is made up of the Sun and the celestial bodies that orbit it: planets, natural satellites, asteroids, comets and meteoroids.
Celestial bodies in the Solar System The Sun is a star at the centre of the Solar System. It is a huge ball made up of gases, mostly hydrogen and helium. The Sun is about 110 times larger than the Earth. Like other stars, the Sun rotates on its axis. It also revolves (orbits) around the centre of the Milky Way. It takes the Sun about 220 million years to complete one orbit.
Look at the picture of the Solar System. Which planet is closest to the Sun?
Kuiper Belt Neptune Uranus
Did you know? Halley’s Comet is the most well known comet. It can be seen from the Earth every 76 years. The last time was in 1986. When will we see it again?
The eight planets that orbit the Sun are classified into two groups: • Mercury, Venus, Earth and Mars are inner planets. They are solid and have a rocky surface. They are warmer and smaller than the outer planets.
Jupiter asteroid belt
• Jupiter, Saturn, Uranus and Neptune are outer planets. These planets are cold and dark because they are far from the Sun. They are called gas giants because they are made up of gases. All the outer planets have rings and many moons. Most of the asteroids in the Solar System are found in two regions: in the asteroid belt, between Mars and Jupiter, and the Kuiper Belt, beyond Neptune.
Natural satellites orbit some of the planets. They are also called moons. Earth has only one natural satellite, but some planets have more than one.
Geocentric and heliocentric models Venus
Our understanding of the shape and size of the Universe has changed over time together with advances in technology. Ancient Greeks believed that the Earth was at the centre of the Universe. According to this geocentric model (‘earth-centred’) the Sun, Moon, planets and stars orbit the Earth. In the 16th century, Nicolaus Copernicus suggested that, in reality, the Earth and other planets orbit the Sun: a heliocentric model (‘sun-centred’). Around 100 years later, Galileo used a telescope to support Copernicus’ theory.
1 What do these sentences refer to?
a. It is the biggest planet in the Solar System. b. They can be found in the Kuiper Belt. c. According to this theory, the Earth is in the centre of the Universe. d. It is the only star in the Solar System. e. This person proved the heliocentric theory.
2 Find out more about the geocentric theory. Draw a picture showing the geocentric model of the Universe. Compare it with the picture of the Solar System above. 3 Explain the difference between a natural satellite and an artificial satellite.
The Earth When do the four seasons start and end?
The Earth is the only planet where life has been found. From space, the Earth looks blue. This is because about 75% of the surface of the planet is water. The Earth moves in two different ways: it orbits the Sun and rotates on its axis.
The Earth’s rotation The Earth rotates anticlockwise on its axis. Earth’s axis is an imaginary line that goes from the North Pole to the South Pole. This line is not perfectly vertical. It is tilted at about 23 degrees. It takes 24 hours for the Earth to complete one rotation. This rotation gives us day and night.
The Earth’s revolution
Did you know? In a darkened room shine a torch onto a globe. Spin the globe slowly anticlockwise. Where is it day? Where is it night?
It takes the Earth just 365 days to orbit the Sun. During this period we experience different seasons because the Earth’s axis is tilted. As a result, our part of the planet receives more or less light during different months. When the Northern Hemisphere is tilted towards the Sun, we receive more sunlight making it summer. During winter the opposite happens: the Earth is tilted away from the Sun and gets less sunlight. The first day of a season is called a solstice or an equinox. The solstices and equinoxes in the Northern Hemisphere are the opposite of those in the Southern Hemisphere. The four seasons
Vernal equinox: 21 March Summer solstice: 21 June
Winter solstice: 22 December night
Autumnal equinox: 22 September
Equinoxes and solstices in the Northern Hemisphere
Day and night
The midnight sun
Day and night vary in length according to the season and your distance from the Equator. At the Equator day and night are approximately the same length all year round. As you get closer to the poles, winter nights become longer. Similarly, the closer you are to the pole the longer summer days become. At the poles the effect is extreme. In summer you experience the midnight sun, while in winter the polar night lasts 24 hours!

The Moon What are artificial satellites?
The Moon is the Earth’s only natural satellite and its nearest neighbour. It is about 384 000 kilometres from the Earth.
Although the Moon is much smaller than the Earth, it has a great influence on our planet. The Moon’s gravity pulls at the ocean water and creates tides. Tides are periodic changes in sea level. Every day we experience two high tides and two low tides.
The Moon is about four times smaller than the Earth. It rotates on its axis and revolves around the Earth. It takes the Moon about 28 days to complete one revolution and the same time to complete one rotation. This is why we always see the same side of the Moon from the Earth. There is no air or atmosphere on the Moon because its gravity isn’t strong enough. The temperature on the Moon varies from -153 ºC at night to 123 ºC during the day. The Moon’s surface is rocky and has craters and mountains. These craters are caused when meteorites hit the surface of the Moon. We can observe these countless craters because the Moon has no atmosphere. There is also no wind or rain on the Moon to erode them.
Eclipses An eclipse occurs when a celestial body moves into the shadow of another. Eclipses can be solar or lunar: The near side of the Moon
• During a solar eclipse, the Moon blocks the sunlight and casts a shadow on the Earth. • During a lunar eclipse, the Earth blocks the sunlight and casts a shadow on the Moon.
The Moon doesn’t produce its own light. We can see the Moon because it reflects sunlight. Obviously we can only see the illuminated part that is facing the Earth. This is why, when we look at the Moon on different nights during the lunar month, its shape changes. These different shapes are called the phases of the Moon. The far side of the Moon last quarter

Build a planetarium
What is space debris?
Aim Understand how a planetarium works and learn about different constellations.
Method 1. In one of the short sides of the box cut a hole of about 7 × 7 cm. 2. Choose several constellations from the constellation charts and find some information about them. 3. On a piece of card draw dots showing the stars of a constellation. Poke holes through the dots with the punch.
• a shoe box • scissors • constellation charts • a pencil • 4 pieces of card (11 cm × 9 cm) • a torch • a punch • tape • a few books
Humans produce a huge amount of rubbish not only on Earth but also in space. Space debris (or space junk) is all the man-made material orbiting the Earth that is no longer used. It includes abandoned satellites, pieces of broken satellites, rocket parts and even human waste. There are more than 20 000 pieces of debris larger than a tennis ball orbiting the Earth. Millions of pieces are too small to be detected.
4. Repeat step 3 for several constellations. 5. Put one of the pieces of card over the hole in the box and tape it. 6. Put a few books inside the box. Put the torch on the books. The torch should point at the corner of the box. 7. Darken the classroom and turn on the torch. Put the lid on the box. Project your constellations on the wall.
The problems with space debris Space debris travels through space at a speed of about 27 000 kilometres per hour. At such speed even a very small object can damage a satellite or a spacecraft. When this happens, even more space junk is created. If debris enters the Earth’s atmosphere, it usually burns up. However, occasionally larger pieces reach the Earth’s surface. Scientists have proposed various solutions to remove space junk, but these continue to be expensive and require very advanced technology.
Conclusions 1 Which constellations did you choose? Find out more about them. Explain the origins of their names. What is the brightest star in each of them? 2 Have you ever noticed that the night sky in winter looks different than in summer? We see different constellations at different times of the year. Why? 3 On a starry night try to identify your constellations. Can you find all of them? Why? 4 Why don’t we see stars during the day?
1 What is space debris? How does it differ from the rubbish that we produce every day? 2 List the problems that space junk creates. 3 Objects that are bigger than a tennis ball are tracked by radars. How can this be helpful? 4 How do think working satellites or spacecraft are protected from space junk? 5
Work with your friend. What could be done to reduce space debris? Think of some possible solutions.
