Europa, also known as Jupiter II, is the smallest of the Galilean moons, behind Io, Callisto, and Ganymede, and is one of the satellites belonging to Jupiter. This moon was found by Galileo Galilei and the less credited, Simon Marius, on January 8, 1610, the day after Ganymede, the largest of Jupiter's natural satellites, was discovered.

It is the sixth largest moon.

FormationEdit

Like many other of Jupiter's moons, no one knows how Europa was formed. Astronomers believe that Europa was a stray meteor in space, and was pulled in by Jupiter's strong gravitational pull.

CompositionEdit

Europa contains an ocean deep inside of the moon, just like Ganymede. Tidal flexing, which is flexing caused by gravitational pulls between surrounding moons, keeps the ocean liquefied.
