Dione orbits Saturn at a distance of more than 200,000 miles away. However, it still only takes Dione 2.7 days for it to complete a full trip around this moon. Dione is actually co-orbital with two smaller moons, named Helene and Polydeuces. This just means that these two moons are orbiting Saturn at a very close proximity to Dione, and follow the same orbiting pattern.
