astronomer have learn 128 never - before - witness Moon orbiting Saturn — grant it almosttwice as many moonsas all the other planets in thesolar systemcombined .
The finding have further bolster Saturn ’s condition as our solar system ’s " moon Billie Jean Moffitt King . " With an update total of 274 known natural satellite revolve the gas giant , it is league ahead of its primary competitor Jupiter , which has just95 confirmed moons .

This week , the International Astronomical Union officiallyrecognizedthe squad ’s find . The researchers published their findings March 10 in the journalarXiv , so they have not yet been peer - reviewed .
" Our cautiously planned multi - yr run has yielded a boom of new moons that tell us about the phylogeny of Saturn ’s maverick innate satellite population , " study lead authorEdward Ashton , an astronomer at Institute for Astronomy and Astrophysics at Academia Sinica , Taiwan , sound out in a command .
The newfound moons are posit within the Norse group of Saturn ’s moons — a group of lunar month that orbit in retrograde ( travel in the opposite direction to the satellite ’s rotation ) along elliptical paths outside Saturn ’s rings . The 128 new give away objects are view " unorthodox " moons , meaning they ’re only a mile or two in size and far from ball-shaped .

Their diminutive sizes and emplacement intend these moons are probable fragment of larger lunar month that were smashed apart by a cataclysmic collision — credibly with Saturn ’s other moon or a pass comet . This hit could have occurred as recently as 100 million age ago , the astronomer said in the study .

The discovery was made using the Canada France Hawaii Telescope ( CFHT ) , which disentangle the sky around Saturn between 2019 to 2021 and light upon an initial 62 additional moons in its orbit . The squad also ascertain faint-hearted signals of an even larger number of orbiting bodies but were ineffective to confirm them at the time .
" With the knowledge that these were probably moons , and that there were probable even more waiting to be discovered , we revisited the same sky fields for three serial calendar month in 2023 , " Ashton enjoin . " Sure enough , we found 128 new moons . Based on our projections , I do n’t think Jupiter will ever catch up . "
The researcher say they are now finished moon - spotting for the foreseeable hereafter , at least until telescopes capable of spotting even fainter signatures are developed .
" With current applied science I do n’t think we can do much better than what has already been done for Moon around Saturn , Uranus and Neptune , " Ashton said .
