I'm going through and re-doing a lecture I last gave 6 months ago, and astronomers are discovering too many new moons!!! (A good problem to have, but still a problem for keeping lectures up to date!)

In the last 6 months:

Uranus has gone from 28->29 https://www.iflscience.com/jwst-spots-tiny-new-moon-just-outside-uranuss-rings-bringing-total-to-29-80480

Jupiter has gone from 95->97 https://www.minorplanetcenter.net/mpec/K25/K25HL0.html

And Saturn has outdone itself... Saturn has gone from 146->274!! Which was of course, partially, accidentally my own fault. https://mastodon.social/@sundogplanets/114179503618251688
