INTRO A dwarf planet is a planet that doesn't meet the current criteria of planethood. There are certain characteristics that a planet has to uphold it to be a planet. Here are the four characteristics all planets need to have. Number one the planet must orbit the sun. Number two the celestial body cannot be a moon. Number three it must have enough mass for it to be round. And last but not least number four it must be able to clear its own path, instead of using another planet's path. To know if the celestial body that you come across is a dwarf planet you would use this checklist.
INTRO The celestial body will be smaller than most planets and lacking some of the known criteria for it to be a planet or moon.the reason Pluto does not meet these criteria is that Pluto does not check of the fourth box on the checklist. Pluto will cross into the planet Neptune's orbit for twenty years on and off. The last time Pluto crossed paths into Neptune's orbit was in 1979, in doing so that made Pluto the eighth planet from the sun instead of the ninth.
Who found pluto Pluto was found by the 1930â€™s astronomer Clyde Tombaugh. Clyde Tombaugh was actually searching for the interruptions in Neptune Orbit when he got close to finding them he found Pluto instead, apparently, Pluto was Interrupting Neptune's orbit. Pluto's surface is icy and hard. Pluto is also the ninth celestial body from the sun and is very near the Kuiper belt.
Who found pluto The Kuiper belt is an asteroid belt is made mostly of rock, ice, and methane. Pluto was named after the Roman god of the underworld. This name was thought of because all of the other planets that were found were named after other gods either from the roman or Greek myths.
On January 19, 2006, a spacecraft with a mission to flyby Pluto, was launched. This mission was crucial to finding the Kuiper belt. this mission was also sent to find ice flows and glaciers on Pluto, and if there were any undiscovered moons that would be great information to know too. The New Horizons Spacecraft took off on January 19, 2006, and came back on July 14, 2015. The New Horizons Spacecraft was unmanned.
Plutoâ€™s moon system Pluto's moon system was formed by a collision with Pluto and the Kuiper belt.Five of Pluto's moons are known to humans.The biggest moon is Charon, it is half the size of Pluto. Charon is also the most known moon in Pluto's moon system. Charon was found in 1978. The other moons are Nix, Hydra, Kerberos,and Styx. Nix and Hydra were found by the Hubble spacecraft in 2005. Kerberos was found in between Nix and Hydra in 2011. Styx was found in 2015 by the New Horizons Spacecraft.
Pluto has a heart-shaped spot on its surface. That spot is made out of rocks, metal, and ice like Pluto itself. Pluto takes 240 earth years to orbit the sun one time. On Pluto there are valleys, ice caps, and frozen nitrogen glaciers also on Pluto when it gets really cold itâ€™s atmosphere freezes and falls like snow, Pluto has blue skies like earth. Pluto is only six percent of earth's gravity. Pluto's orbit is more ovalish then circular, Pluto also rotates on its side. There are three dwarf planets including Pluto their names are Chris and ceres.
CONCLUSION Pluto is an important planet to learn about because There used to be lots of controversy about it being a planet or a dwarf planet. They finally decided on it being a dwarf Planet but lots of people argue that it should still be a planet. Pluto is different because it has different facts than most planets. Since it is a dwarf Planet it has more interesting and unique things about it.
CONCLUSION There are only three dwarf planets that we know about and most of them we haven't even seen. In conclusion, Pluto is very interesting to learn about and with this unique information, you might even be able to impress your teachers.
