How large is Jupiter’s biggest moon?
Size. Ganymede is the largest and most massive moon in the Solar System. Its diameter of 5,268 km is 0.41 times that of Earth, 0.77 times that of Mars, 1.02 times that of Saturn’s Titan (Solar System’s second largest moon), 1.08 times Mercury’s, 1.09 times Callisto’s, 1.45 times Io’s and 1.51 times the Moon’s.
What are the 4 moons?
The four moons are Io, Europa, Ganymede, and Callisto, in order of distance from Jupiter. (Their names derive from lovers of Zeus.) These moons provided evidence that not all celestial bodies orbit the Earth, a powerful revelation as, up until that time, astronomers considered Earth the center of the universe.
What 4 moons did Galileo?
In January 1610, Italian astronomer Galileo Galilei discovered four of Jupiter’s moons — now called Io, Europa, Ganymede and Callisto.
Why does Jupiter have 79 moons?
The further you travel from the sun, the weaker its gravitational pull on you becomes. Therefore, if Namouni is correct, the real Jupiter has 79 moons and counting because it’s an insanely massive planet that’s far enough away from the sun to avoid lunar theft.
Who discovered the moon?
Earth’s only natural satellite is simply called “the Moon” because people didn’t know other moons existed until Galileo Galilei discovered four moons orbiting Jupiter in 1610.

What is the largest moon of Saturn?
Saturn’s largest moon, Titan, is an icy world whose surface is completely obscured by a golden hazy atmosphere. Titan is the second largest moon in our solar system. Only Jupiter’s moon Ganymede is larger, by just 2 percent. Titan is bigger than Earth’s moon, and larger than even the planet Mercury.
What is the smallest moon of Jupiter?
Astronomers have pinned down details of Jupiter’s smallest known moon, a tiny space rock barely a mile across. The moon, known as S/2010 J 2, was discovered in September 2010 along with a fellow shrimpy satellite called S/2010 J 1.
What is the biggest moon in the universe?
