While Earth’s one and only moon enthralls everyone on this planet, it can’t hold a candle to Saturn’s 274 moons, 128 of which were recently discovered and recognized by the International Astronomical Union. With this new surge in its moon count, Saturn prevails with the most moons out of any other planet in the Solar System.

Astronomers are now wondering, though, how this abundance of moons emerged in the first place.
