More Moons around Jupiter & Saturn

Astronomers have discovered nine new moons. The astronomers found eight new moons of Jupiter and one new moon of Saturn. Jupiter has 60 moons that we know about. Saturn has 31.

All of the new moons are small. The new moons of Jupiter are about two or three kilometers (a mile or two) across. The new moon of Saturn is about eight kilometers (five miles) across.

Astronomers found twelve new moons of Jupiter earlier this year. They found several new moons of Saturn more than two years ago. Scientists think there are many more small moons that haven't been found yet. A spacecraft called Cassini is on its way to Saturn. When it gets there, it may find more moons around Saturn!
