Jupiters Chemistry

• 86 hydrogen
• 13 helium
• 1 other stuff
• methane CH4
• ammonia NH3
• water vapor H2O

10
The light zones are regions of hotter, rising
gas, while the dark belts are regions of cooler,
descending gas.

• (or vice versa!)

11
Jupiters interior has three distinct regions

• Upper atmosphere of clouds and gas
• Middle layer of liquid metallic hydrogen
• Small rocky protoplanet core

12
Pieces of Comet Shoemaker-Levy 9 fragments
collided with Jupiter in 1994
13
Jupiter is orbited by four large moons and many
small ones

• 52 total at last count
• (12 more discovered last month!)

Saturns banded surface and layered interior are
similar to those of Jupiter
26
Saturns spectacular rings are composed of
fragments of ice and ice-coated rock

moons and keep the F ring to a band about 100km
wide because of gravitational effects.
