The planet Jupiter takes 4331.6 earth days to orbit around the Sun. This means than one Jupiter year equals almost 11.9 Earth years. Because Jupiter rotates so rapidly around its axis, its year lasts 10,501 of its own days. Jupiter has such a long year because it is quite far from the Sun. Not only does this mean it has a longer path to travel on its orbit, but the Sun’s gravity is much weaker at that distance, requiring it to move more slowly to stay in its orbit.
