Moons of our Solar System

How many moons of planets, dwarf planets, and possible dwarf planets in our Solar System can you name?
Charon is in grey, as it acts like a dwarf planet in multiple ways.
Asteroid moons tend to be uncounted as JetPunk only allows me 500 answers, there are over 400 known asteroid moons.

Euridome is spelled wrong. It should be Eurydome.

I was adding "Ganymedes" and, for some reason, all the S/2001 to S/2018 appeared !

So my score is 64, even though I would really tiped eight moons!

I'd assume it's because you typed 's' at the end, since Ganymede doesn't have an s it filled the S/[year] moons. Good score either way, there's not many moons known by people :)

it actually wasn't missing, it was under the designation S/2004 S 30, since it was named after the quiz was made. It and 9 other moons were named together in August 2022, and I just didn't notice, oops. Thank you for pointing this out, those 10 have been fixed.
