The Outer Planets: Jupiter, Saturn, Uranus, Neptune - The outer planets are furthest from the sun. - They are: Jupiter, Saturn, Uranus, and Neptune - These are giant planets called Jovian Planets, Planets, named for Jupiter. - Made mostly of gas so they have low density. density. Mr. Fetch’s Earth Science Classroom The Outer Planets: Jupiter, Saturn, Uranus, Neptune, Pluto Most of the Jovian planets have the same structure: structure: - Outer parts ALL gas: H, He, and Methane THEY DO NOT HAVE A SOLID SURFACE! H, He, and Methane Gas Small Core Mr. Fetch’s Earth Science Classroom 1 The Outer Planets: Jupiter - The biggest planet of all. - 300x’ 300x’s the mass of Earth. - It takes 12 years to go around the sun. (year is 12x’ 12x’s as long) Mr. Fetch’s Earth Science Classroom The Outer Planets: Jupiter - Jupiter’ Jupiter’s atmosphere is thick with H and He gas. - Bands of clouds (red, white) from high and low pressure systems. systems. Great Red Spot - Giant storm - 2x’ 2x’s the size of earth - 300 years old Mr. Fetch’s Earth Science Classroom 2 The Outer Planets: Jupiter - Jupiter has 61 moons. - It sucks in lots of moons because of its high gravity. gravity. - Jupiter is often called a “mini solar system” system” for this reason. IO EUROPA GANYMEDE CALLISTO Mr. Fetch’s Earth Science Classroom The Outer Planets: Saturn - Saturn is the second largest planet., but is the least dense. dense. - It’ water!!! It’s density is so low that it could actually float in water!!! - Saturn has amazing rings. rings. - Rings are ice and dust. dust. - Rings are wide, but paper thin. - Gravity holds them around planet. Mr. Fetch’s Earth Science Classroom 3 The Outer Planets: Saturn Great White Spot --- Saturn has a Great White Spot - Large atmospheric storm system Mr. Fetch’s Earth Science Classroom The Outer Planets: Uranus - Uranus is blue from methane gas. gas. - High temperature and pressure make it rain diamonds !!! Mr. Fetch’s Earth Science Classroom 4 The Outer Planets: Uranus - Pictures of Uranus were taken by Voyager 2. - They noticed that Uranus rotates on its side. side. - A space collision toppled it over. Mr. Fetch’s Earth Science Classroom The Outer Planets: Neptune - Neptune is also blue from Methane gas. - It is also thought to be raining diamonds !!! - Neptune has a Great Dark Spot. Spot. - Another very large atmospheric storm. storm. - Has recently disappeared (1994). Mr. Fetch’s Earth Science Classroom 5 Pluto - It is SOLID made of rock and ice. - It is not made of gas Not a planet !!! Mr. Fetch’s Earth Science Classroom The Outer Planets: Pluto - It takes 248 Earth years to revolve once around the sun. IT HAS THE MOST ELIPTICAL ORBIT. ORBIT. - Take longest to revolve. - Crosses Neptune’ Neptune’s orbit. Becomes 8th planet instead of 9th for a time... Mr. Fetch’s Earth Science Classroom 6
