Saturn overtakes Jupiter as planet with most moons

A team discovered a haul of 20 new moons orbiting the ringed planet, bringing its total to 82; Jupiter, by contrast, has 79 natural satellites. Each of the newly discovered objects in orbit around Saturn is about 5km (three miles) in diameter; 17 of them orbit the planet “backwards”. The moons were discovered using the Subaru telescope on Maunakea, Hawaii.
