Editing Galilean Moons

The four '''Galilean Moons''' of [[Jupiter]] refer to the astronomer [[w:Galileo Galilei|Galileo Galilei]] who is credited with identifiying them in 1610.They are by far the largest of the many moons of Jupiter. In order from closest they are [[Io]], [[Europa]], [[Ganymede]], and [[Callisto]]. Io, Europa, and Ganymede are locked into a 1:2:4 orbital resonance, Callisto is not, but, all four moons are locked into a tidal rotation, keeping the same face toward Jupiter throughout their orbits.

Galileo first named the moons Gosmica Sidera (Cosimo's stars), but the names that caught on were given by [[w:Simon Marius|Simon Marius]] who independently observed the moons about the same time as Galileo. See [[w:Galilean moons|Galilean moons]] at Wikipedia.
