Jupiter has something like 90+ moons. I'm not going to count.
When I started astronomy they told me 60.
We just keep learning more and more.
Anyway, the big 4 can be remembered
"I Eat Green Cows" (Io, Europa, Ganymede, and Callisto)
A lot of the others also have names.
I'm just telling you all this so I can show you this gif of some moons orbiting Jupiter.
