Now its smaller sibling Saturn has stolen the crown, as astronomers have discovered no less than 20 new moons around the ringed planet. That brings its total to 82, three more than Jupiter.
The new moons were discovered by a team of scientists from Carnegie Science, University of California Los Angeles (UCLA) and the University of Hawaii, using the Subaru Telescope on Hawaii. The announcement was officially made by the International Astronomical Union's Minor Planet Center.
All of these moons are around 5 km (3 mi) wide, and one of them is the most distant moon circling Saturn. Like most of Saturn's moons, 17 of the 20 newly discovered rocks orbit in a retrograde direction, meaning they move in the opposite direction to the spin of the planet. The three remaining moons move with the planet, in a prograde direction.
