Mo13-L3a: How are the Outer Planets Similar?

Jupiter

Jupiter is the largest planet in the solar system.

Jupiter has a diameter 11 times larger than the diam- Io Europa Ganymede Callisto
eter of Earth.

Temperature

Jupiter’s atmosphere is about 90 percent hydrogen
and 10 percent helium.

The planet itself is about 80 percent hydrogen and
20 percent helium.

Jupiter is a ball of gas swirling around a thick liquid
layer that conceals a solid core. Scientists are not SUMMARY
certain what makes up the core.
How are the Outer Planets Similar?
Jupiter has at least 63 moons, more than any other
planet. All of the outer planets are primarily made of
materials that are gases on Earth. Colorful
clouds of gas cover Saturn and Jupiter.
The four largest moons of Jupiter - Io, Europa,
Ganymede, and Calisto—are known as the Galilean
moons. Jupiter is the largest outer planet. Its four
largest moons are known as the Galilean
moons.
The Galilean moons are made of rock and ice.
