.The King of the Planets may not have the best moons, however 4 of Jupiter's 95 moons are certainly the simplest to see with a little set of field glasses or even a tiny telescope given that they create a very clear line. The Galilean Moons-- Ganymede, Callisto, Io, as well as Europa-- were actually initial discovered in 1610 and also they continue to blow away around the world.
