Europa (pronounce /jʊˈroʊpə/ yew-ROE-pə listen (help·info); or as Greek Ευρώπη) is the sixth moon of the planet Jupiter. Europa was discovered in 1610 by Galileo Galilei (and, some say, independently by Simon Marius), and named after a mythical Phoenician noblewoman, Europa, who was courted by Zeus and became the queen of Crete. It is the smallest of the four Galilean moons.
