Jupiter. It's one of the Galilean satellites, discovered in 1609.
Because it is the result of tidal heating from friction in the interior of IO as it's pulled between Jupiter and the other Galilean satellites.
The four satellites are Jupiter's largest moons. They were found by Galileo Galilei. They are Callisto, Europa, Ganymede and Io.
Jupiter actually has many satellites. As of February 2004, Jupiter had a confirmed number of 63 satellites, ranging from the largest four, the Galilean moons, Ganymede, Io, Callisto, and Europa. 53-55 of Jupiter's satellites are tiny and unimportant, small space objects caught in the planet's gravity
The four biggest satellites of Jupiter are Ganymede, Callisto, Io, and Europa. Ganymede is the largest moon in the solar system and is even bigger than the planet Mercury. These four moons are known as the Galilean moons, named after Galileo Galilei who discovered them in 1610.
Jupiter has 66 natural satellites. Of these, 50 are less than 10 kilometres in diameter and have only been discovered since 1975. The four largest moons, known as the "Galilean moons", are Io, Europa, Ganymede and Callisto.
