Jupiter’s temporary however wonderful reign because the planet with the most moons in our solar system got here crashing down this week as scientists confirmed the invention of 62 new moons orbiting Saturn — bringing the ringed planet’s complete to a whopping 145 moons.
That is a decisive leap forward of Jupiter’s 95 confirmed moons – a complete that eclipsed Saturn’s moon rely for a number of months after 12 new moons had been formally acknowledged orbiting Jupiter in late December. Saturn is now the primary and solely planet within the photo voltaic system with greater than 100 recognized moons, based on researchers on the University of British Columbia (opens in new tab) (UBC), who aided within the new discoveries.
The workforce of worldwide researchers made their detections utilizing knowledge from the Canada-France-Hawaii Telescope on high of Mauna Kea, Hawaii between 2019 and 2021. By analyzing a trove of sequential pictures taken over 3-hour remark home windows, the workforce recognized 62 moons that had been beforehand both too small or too dim to detect. A few of the smaller moons measured simply 1.6 miles (2.5 kilometers) large — a distance smaller than the size of the Nationwide Mall in Washington, D.C.
All the 62 newly detected moons are “irregular moons,” which means they comply with distant, elliptical orbits round their host planet and infrequently transfer in retrograde — or in the wrong way of Saturn’s rotation. Many of those tiny, oddball moons clump collectively in related retrograde orbits, suggesting they could have originated from a bigger guardian moon that broke aside tens of millions of years in the past, based on the researchers.
“As one pushes to the restrict of contemporary telescopes, we’re discovering rising proof {that a} moderate-sized moon orbiting backwards round Saturn was blown aside one thing like 100 million years in the past,” Brett Gladman (opens in new tab), a professor of astronomy and astrophysics at UBC, mentioned in an announcement.
The brand new moons are anticipated to be acknowledged later this month by the Worldwide Astronomical Union — a gaggle of greater than 12,000 scientists answerable for designating celestial our bodies, amongst different issues.
Jupiter couldn’t be reached for remark.
