As of 2020, there are over 600 moons in our Solar System. In the past few years, many new moons have been discovered, and it is believed that many others are yet to be found. We know of 204 moons that orbit planets, 309 asteroid moons, eight dwarf planet moons, and 111 other trans –Neptunian moons. This sums up to a total of 632 moons.
