More and more Moons of Jupiter
News story originally written on March 20, 2003
Astronomers have discovered twelve new moons of Jupiter
so far this year. Jupiter is the largest planet in our Solar System. It has
more moons than any other planet. Jupiter has 52 moons that we know about.
All of the new moons are very small. The biggest ones are only about four kilometers
(about two and one-half miles) across. You could walk all the way around them
in a day or two!
The moons were discovered using telescopes on the top of a volcano in Hawaii.
