As of now, there are 66 known moons. The four main ones are Io,
Ganymede, Callisto, and Europa. Those moons of Jupiter are the
largest moons of Jupiter.
There are some other moons of Jupiter, the smaller ones. Some of
them are
Thebe, Amalthea, Thelxinoe, Isonoe, Autonoe, and Carpo. I was
only telling you how many moons are there, some of their names, and
sorry I didn`t include the rocks in the ring of Jupiter.
