Detailed explanation-1: -In addition to being the largest planet in our Solar System – with two and a half times the mass of all the other planets combined – it also has the most moons of any Solar planet. So far, 67 natural satellites have been discovered around the gas giant, and more could be on the way.

Detailed explanation-2: -Jupiter has 67 known moons-the most of any planet in the solar system-and more are expected to be discovered by the Juno spacecraft. There are three main moon groups, the first being the four primary Jovian satellites. They were discovered by Galileo on Jan. 7, 1610, with his low-powered telescope.

Detailed explanation-3: -The German astronomer Simon Marius claimed to have seen the moons around the same time, but he did not publish his observations and so Galileo is given the credit for their discovery. These large moons, named Io, Europa, Ganymede, and Callisto, are each distinctive worlds.

Detailed explanation-4: -Jupiter has at least 67 known moons ( http://solarsystem.nasa.gov/planets/jupiter/moons ). The largest four are called Io, Europa, Ganymede, and Callisto. These four moons are called the Galilean satellites because they were first seen in 1610 by the astronomer Galileo Galilei.

Detailed explanation-5: -67 moons orbit the great gas giant Jupiter; of these, the four largest are known as the Galilean moons, having been discovered by Galileo Galilei using his telescope in 1610.
