None, Saturn's moon Titan has a thick, nitrogen-rich atmosphere.
Titan, a moon of Saturn, has a thick atmosphere mainly composed of nitrogen. Jupiter's moon Ganymede has a thin atmosphere made up of oxygen.
Ganymede is the largest Galilean moon, the largest Jovian moon, and the largest moon in the solar system.
Callisto with a semi major axis of 1,882,700 km. See related question.
Titan, a moon of Saturn, has a dense atmosphere composed mostly of nitrogen with traces of other gases like methane and ethane. Its atmosphere is thicker than Earth's and plays a significant role in its weather patterns.
Titan is a solid. The moon itself is primarily composed of water ice and rocky material.
Titan, a moon of Saturn, has a thick atmosphere mainly composed of nitrogen. Jupiter's moon Ganymede has a thin atmosphere made up of oxygen.
No. It is a moon of Mars. The Galilean moons are moons of Jupiter.
The two planets that are mostly composed of methane and nitrogen are Uranus and Neptune. These gas giants have thick atmospheres made up primarily of methane and nitrogen, with smaller amounts of other gases such as hydrogen and helium.
Ganymede is the largest Galilean moon, the largest Jovian moon, and the largest moon in the solar system.
Yes. The moon is made mostly of rock but has a small nickel-iron core.
Charon is a moon of Pluto. [See related question] To be a Galilean moon you have to be one of the four major moons of Jupiter.
Jupiter.
Europa
Titan is not made of gas. It has an interior of rock with outer layers composed mostly of ice. Titan's atmosphere is made primarily of nitrogen and methane.
What? No, Triton barely has any sort of atmosphere. The only Moon with an atmosphere composed of more than trace gases is Titan, the largest moon of Saturn. Its atmosphere is 1.5 times as dense as Earth's and composed mostly of Nitrogen and Methane.
Callisto with a semi major axis of 1,882,700 km. See related question.
Ganymede is the Galilean moon known for having a grooved terrain. These grooves are believed to be the result of tectonic activity on the moon's surface.
