49 moons as of January 2009, 14 are still in consideration
Jupiter has 63 confirmed moons that are in a stable orbit around the planet. There could well be more than this though, which have yet to be discovered.
Callisto is the 2nd largest and 8th closest of Jupiter's known moons, with an orbit about 1.8 million km from Jupiter. It was discovered by Galileo in 1610 and is the most distant from Jupiter of the 4 large Galilean moons. Jupiter's large moons orbit rapidly compared to Earth's Moon. Callisto circles Jupiter every 16.7 Earth days.
There are no moons in Jupiter. Jupiter does have 63 confirmed that are in a stable orbit around the planet though. There could well be more than this though, which have yet to be discovered.Jupiter have 64 moons.
Many astronomers have discovered Jupiter's moons. Galileo discovered the first four moons of Jupiter, named Calisto, Europa, Ganymede and Io.
62 moons orbit Saturn, 67 orbit Jupiter, 5 orbit Pluto, 14 orbit Neptune, and 27 orbit Uranus.
The Galilean moons are located around the planet Jupiter. They were discovered by Galileo Galilei in 1610 and are named Io, Europa, Ganymede, and Callisto. These moons are the largest of Jupiter's many moons and are known for their distinctive features, such as volcanic activity on Io and the possibility of liquid water on Europa.
Jupiter has about 63 Moons, discovered so far.
10 -------- Jupiter has 67 known moons in orbit.
The Galilean moons are Io, Europa, Ganymede, and Callisto, all of which orbit Jupiter. The term "Galilean" does not denote anything special about the moons other than that they were discovered by the astronomer Galileo Galilei.
The moon we see doesn't, but all of Jupiter's moons do. (About 50)
Jupiter has 63 moons discovered to date. Some names of Jupiter's moon are Io, Europa, Ganymede, Callisto and many more.
My answer is four moons that Galileo found on or near Jupiter.
