Saturn overtakes Jupiter as planet with most moons

Saturn has overtaken Jupiter as the planet with the most moons, according to US researchers. 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. The moons were discovered using the Subaru telescope on Maunakea, Hawaii.

Each of the newly discovered objects in orbit around Saturn is about 5km (three miles) in diameter; 17 of them orbit the planet "backwards". This is known as a retrograde direction. The other three moons orbit in a prograde direction - the same direction as Saturn rotates. Two of the prograde moons take about two years to travel once around the ringed planet. The more-distant retrograde moons and one of the prograde moons each take more than three years to complete an orbit.

Name the moons. Full list.

    Too bad Agena was lost when the thruster defect was in the capsule.

    Are two stars enough to be called a constellation? How about only one star?

    Yeah but it's an entirely bullshit constellation:
