    Jupiter currently has the largest known number of satellites in the solar system, with 67 known moons (as of August 2014). The four largest moons were discovered by Galileo Galilei and are called the Galilean Satellites or moons. They are Callisto, Europa, Ganymede, and Io, with Io having the closest orbit to Jupiter. And Ganymede is larger than planet Mercury.
