Explanation:

Jupiter's four largest moons – aka. the Galilean moons, consisting of Io, Europa, Ganymede and Callisto – are nothing if not fascinating. Ever since their discovery over four centuries ago, these moons have been a source of many great discoveries. These include the possibility of internal oceans, the presence of atmospheres, volcanic activity, one has a magnetosphere (Ganymede), and possibly having more water than even Earth. Like all the Galilean satellites, Europa was named after a lover of Zeus, the Greek equivalent to Jupiter. Europa was a Phoenician noblewoman and the daughter of the king of Tyre, who later became a lover to Zeus and the queen of Crete. The naming scheme was suggested by Simon Marius – a German astronomer who is thought to have discovered the four satellites independently – who in turn attributed the proposal to Johannes Kepler.

These names were not initially popular and Galileo refused to use them, opting instead for the naming scheme of Jupiter I – IV – with Europa being Jupiter II since it was believed to be the second closest to Jupiter. However, by the mid-20th century, the names suggested by Marius were revived and entered common usage.
