FC: The Dwarf Planet Known As Pluto By Joe, Darius, and Travis
1: Pluto was discovered in 1930 by Clyde Tombaugh. One day he was looking through his telescope and found Pluto. Although Pluto was considered a planet for a long time, sadly it became a Dwarf Planet in 2006.
2: Pluto's average temperature is -375 degrees. The atmosphere can freeze onto Pluto's surface. Also the atmosphere is made up of Nitrogen, Methane, and Carbon Dioxide.
3: There are 3 moons on Pluto. They are Charon, Nix, and Hydra. Charon is the biggest one spanning about half as big as Pluto. Nix is only about 46 km. across and Hydra is 61 km. across.
4: Pluto's mass is 1250 kg. | At it's farthest point away from the sun it is 4,853 billion miles. At it's closest point it is 2,757 billion miles. | It's diameter is 1,400 miles, or 2080 kilometers.
5: Since Pluto is so cold the main thing that's on it is ice. Also ice pretty much makes up the surface, that or snow. Pluto also has three different layers of ice. They are all methane ice. So if you decide to take a trip to Pluto, make sure you pack your Snuggie.
6: Pluto does not have very much gravity at all. In fact it is about 10% of Earth's gravity. So if you were there you would float all over the place.
7: What's the difference between a dwarf planet (Pluto) and a regular planet? Well mainly it's all about the size. You have to be a certain size to be a planet. Also you must be able to fling things out of your orbit. If you can't you are a dwarf.
8: One Pluto day is about 6 Earth days. It takes about 250 Earth years to make one revolution. Pluto's axis is tilted at 123 degrees. It's density is 2030 kg./m cubed. The surface is made up of about 30% water and about 70% rock. There is not very much sunlight at all on Pluto. In fact only about 15% of Earth's. The sun would also look like a star from Pluto.
9: In 2005 the New Horizon Mission was launched. If successful it will land on Pluto in 2015. Then it will return to Earth in 2025.
