outer planet project
Jupiter is the largest planet in the solar system, It's diameter is 11 times bigger than earth's. Jupiter's mass is twice the size as all the planets combined. 1,000 earths can fit in side Jupiter. Jupiter's atmosphere is 1,000 km thick. Jupiter is 80 percent hydrogen and 20 percent helium. the pressure is so great that the gasses change to liquid. Jupiter has 63 moons.
Jupiter: the Largest
Saturn is the sixth planet from the sun. It is the least dense planet. it's density is less than water. Saturn has a solid core. Saturn has the largest rings in the solar system. It's has seven bands of rings, each containing thousands of narrower ringlets. the ring s are 70,000 km wind but less than 30 m thick. the ice in the rings are probably from a moon that broke when some thing hit it. Saturn has at least 60 moons. the Cassini orbiter released the Huygens probe that landed on one of Saturn's moons called Titan.

Uranus is the 7th planet from the sun. Uranus has faint rings that are narrow. Uranus has a deep atmosphere made of mostly of hydrogen and helium. Uranus has a tilted axis so it looks like a rolling ball in space. Uranus has at least 27 moons. the two largest moons are smaller than earths.
Space School - Uranus
Neptune was found in 1846. Neptune has an atmosphere like Uranus, mostly made of hydrogen and helium with a trace of methane. Neptune's core is smaller than Uranus's core. partly frozen water and ammonia with rock and iron core.
