.The King of the Planets could not have the best moons, however 4 of Jupiter's 95 moons are actually absolutely the best to find with a small pair of field glasses or a little telescope because they develop a very clear line. The Galilean Moons-- Ganymede, Callisto, Io, and also Europa-- were very first found in 1610 as well as they remain to amaze stargazers around the world.
