Jupiter

Jupiter.

Jupiter, a planet in our Solar System, currently has 69 confirmed moons. 46 of these are less than 3 km wide and probably used to be asteroids before Jupiter's gravity pulled them in. This gives it the largest retinue of moons with "reasonably secure" orbits of any planet in the Solar System. The most massive of them, the four Galilean moons, Io, Europa, Ganymede, and Callisto, were discovered in 1610 by Galileo Galilei and Simon Marius. They were the first objects found not to orbit a body that was neither Earth nor the Sun. The Galilean moons are by far the largest and most massive objects in orbit around Jupiter, with the remaining 65 moons and the rings together comprising just 0.003% of the total orbiting mass.

From the end of the 19th century, dozens of much smaller Jovian moons have been discovered and have received the names of lovers, conquests, or daughters of the Roman god Jupiter, or his Greek equivalent, Zeus.
