.The King of the Planets might not have the best moons, but 4 of Jupiter's 95 moons are certainly the best to observe along with a little pair of field glasses or a little telescope due to the fact that they form a very clear line. The Galilean Moons-- Ganymede, Callisto, Io, and also Europa-- were initial found out in 1610 and also they remain to amaze stargazers around the world.
