Our Solar System By: Sam, Dean, and Meghan The Sun The sun’s core is 15,000,000 degrees Celsius. The sun is a million kilometers across. You could fit more than I million Earths inside of it. The Moon The Moon is 384,400 kilometers from Earth. It has many craters, valleys, mountains, and old volcanoes sights. Earth Earth is 4.5 to 4.6 billion years old. More than 50% of Earth is water. The Earth has 2 ice caps from the top to bottom. Earth is the only planet humans walked on. Mercury It takes 87.969 days to orbit the sun. It has no moons. It was once believed that Mercury had no water. Jupiter Jupiter is one big gas planet, 90% of it is hydrogen, 10% is helium. You can fit 1,000 Earths inside Jupiter. It is know to have 62 moons, 49 are named. Uranus Uranus has 27 moons. It is the 7 planet from the sun. Scientist think that there are more in the rings. It is mostly made of rocks and different type of ices. There are thirteen moons unnamed. Saturn Saturn is know as a giant gas planet. It is made up of 75% of hydrogen and 25% helium. It’s rings are made of mostly water, ice, and may also include rocks with a icy coating. Mars Mars is a small rocky planet that is cold and lifeless. It has very strong winds and very strong sand storms, it sometimes blow throw the whole entire planet. It has two moons called Phobos and Deimos. Neptune Neptune is a giant gas planet which is mostly like various ices and rock. It has 13 moons all are named. It is the 8 planet away from the sun. Pluto One rotation is 6 days and nine hours. It takes 90,465 days to go around the sun. It has one moon named Charon. It is a small dwarf planet and NASA is thinking about making it not a planet. Asteroid Belt Asteroids are mostly made of metal and rocks. The Asteroid Belt separates the inner planets from the outer planet. It is in between Mars and Jupiter. Scientist think that the Asteroid Belt was from planets that were never formed.
