Ch. 3 Sec. 4 Outer Planets
made up almost entirely of gases
outer planets Jupiter Saturn Uranus Neptune Pluto gas giants
Jupiter is more than 300 times as massive as Earth. Jupiter, King of the Roman gods
4 largest moons-
Io- active volcanoes
Europa- icy crust - liquid H 2 0 under
Callisto- icy surface with craters
Great Red Spot = ongoing hurricane most massive planet
Jupiter is really big !
Jupiter with one of its many moons.
Europa There are currently 63 known moons orbiting Jupiter. These are the largest four. Callisto Io Ganymede
View of Jupiter from Voyager 1 Jupiter’s Great Red Spot
Saturn Family Tour video 31 known moons- largest = Titan hundreds of rings- made of chunks of ice & rock 2 nd largest planet
Titan, the Largest Moon of Saturn
very thick atmosphere which is mostly nitrogen
bigger than both Mercury and Pluto
For all their solid appearance, in truth, Saturn's splendid rings are composed of trillions of separate objects – ranging from house-sized “boulders” all the way down to tiny specks of dust measuring just millionths of an inch across.
interactive puzzle about Saturn
Saturn, god of harvest or time of reaping (sixth planet from the sun).
Uranus, father of Saturn and grandfather of Jupiter
rotates on its side from top to bottom
axis tilted at 90 o angle
possibly caused by collision w/ another object
at least 22 moons discovered by William Herschel in 1781 looks bluish methane gas in atmosphere
The Great Dark Spot Neptune, Roman god of the sea at least 13 moons largest = Triton Great Dark Spot- similar to Jupiter’s Great Red Spot
Pluto, Greek god of wealth, ruled the dark underworld
Not a planet anymore-minor planet
discovered by Clyde Tombaugh in 1930
3 moons- largest= Charon
close in size & close together
smaller & denser than gas giants-
smaller than Earth’s moon
Two small moons have been discovered orbiting Pluto , bringing the planet's known satellites to three.
