In astronomical units Jupiter is 5.203 Aus from the sun , which translates into 778.3 million kilometers. It s day is approximately 9 Earth hours long, and it takes 11.86 of our years before Jupiter completes one of it s own.

It was recently discovered that Jupiter has a faint ring of it s own, just as some of the other outer planets do. In contrast to Saturn s bright rings Jupiter s rings are darker for some at the moment unknown reasons. The pull of gravity is well over twice that of Earth and it gives off approximately twice the heat that it take in from the sun . The moons of Jupiter are very fascinating in and of themselves.
