Ganymede is the largest moon of Jupiter, and it orbits the planet at an approximate distance of 665,115 miles, according to NASA. Jupiter orbits the Sun in an elliptical orbit, ranging from 460,237,112 at its closest approach to 507,040,015 miles away when it is at its most distant.
So, depending on the position of both Jupiter and Ganymede, the moon could be anywhere from 459,571,997 to 507,705,130 miles from the Sun. Ganymede is larger than Mercury and Pluto, and three-quarters the size of Mars. It was discovered by Galileo Galilei on January 7, 1610, and was the first moon discovered orbiting a planet other than Earth.
