Ganymede- Jupiter Moon

Ganymede is a moon of Jupiter. Ganymede is larger than Mercury and Pluto. In fact, if it orbited the sun, it would probably be a planet because it's so big. Ganymede is the largest moon that Jupiter has. Galileo was the first to name Jupiter's moons, but later on the moons, including Ganymede, were renamed in honor of mythical companions of Jupiter. The discovery of Ganymede was when people figured out there were moons for other planets, and not everything orbited Earth.

The three layers that make up Ganymede are iron, rock, and ice. Ganymede has a very thin atmosphere. Scientist got all their information about Jupiter's moons from the Hubble telescope. The dark spots on Ganymede are from the craters and the light spots are grooves on the surface. The diameter of Ganymede is 3,300 miles.

Ganymede is 4.5 billion years old, it's about the same age as Jupiter. Ganymede orbits at 650,000 mph. Also, it takes Ganymede about 7 earth days to orbit Jupiter. Ganymede's daytime temperature gets to -171 to -297 F. At night the temperature gets to a low of -315.4 F.
