Saturn is Winning the Moon Contest

So Saturn now has 145 moons due to the discovery of 62 new moons, which is 50 more than the next closest competitor, Jupiter, with 95 moons. You can thank the University of British Columbia (UBC) for the new moon count.

The new discoveries come from a process used by UBC astronomers called ‘shift and stack’:

Shifting a set of sequential images at the rate that the moon is moving across the sky results in enhancement of the moon’s signal when all the data is combined, allowing moons that were too faint to be seen in individual images to become visible in the stacked image. The team used data taken using the Canada-France-Hawaii Telescope (CFHT) on top of Mauna Kea, Hawaii between 2019 and 2021. By shifting and stacking many sequential images taken during three hour spans, they were able to detect moons orbiting Saturn down to about 2.5 kilometres in diameter.

So, as you can read, some of these moons are pretty small. As of today, NASA was still showing 124 moons around Saturn, and another site,, is showing only 62 moons total around the planet. It appear the space agency and others will need to update their pages to show the new mini-moons.

For some reason I doubt the counting is over, just like identified dwarf planets, that seem to range from 5 to 19 at the moment, depending on the source.
