If planets have been aggressive, Saturn can be taking a fist-pumping victory lap proper now. 

A group of scientists led by Carnegie Establishment for Science astronomer Scott S. Sheppard has discovered 20 new moons in orbit round Saturn, bringing the planet’s complete as much as 82. Hold your gas-giant head in disgrace, Jupiter, you solely have 79 recognized moons. Carnegie is now hailing Saturn as the brand new “king of moons.”

These moons have slipped previous scientific scrutiny partially as a result of their small dimension. Every one is simply about three miles (5 kilometers) in diameter. Most of them orbit the ringed planet in the other way that it rotates (retrograde). Solely three orbit the opposite method (prograde).

“Finding out the orbits of those moons can reveal their origins, in addition to details about the circumstances surrounding Saturn on the time of its formation,” mentioned Sheppard in a launch from Carnegie on Monday.

The group tracked down the moons utilizing the Subaru telescope in Hawaii. Saturn’s spectacular complete doesn’t suggest Jupiter is out for the rely. The researchers introduced the discovery of 12 new moons round Jupiter in 2018. There is perhaps extra hiding out round each of those moon-crazy planets.

Carnegie ran a competitors to call a few of Jupiter’s moons, and it’ll run an analogous competitors to give you acceptable names for Saturn’s brood. Neglect Moony McMoonface, although. The assorted pure satellites have to be named for giants from Inuit, Norse and Gallic mythology. 

The Worldwide Astronomical Union is the ultimate arbiter of names, so you possibly can assessment the IAU’s naming tips earlier than submitting your concepts.

Saturn’s moon horde highlights the tempo of latest house discoveries. From interstellar objects to peering in on the birthplace of dual child stars, we’re studying extra about our wacky universe on a regular basis.
