Jupiter's Moons

Last night we heard that we could see Jupiter and it's four moons.
So we went outside and ate a picnic dinner while we watched the moons.

Jupiter is only separated from us by one planet. Mars.

So we got our binoculars. Put them on our tripod and watched the moons and got to see them move across the sky.
Pretty cool!

Jupiter's four moons are:
Europa, an icy moon.
Io is a colorful moon because of all the sulfer.
Callisto; all ice and rock.
And Ganymede is a lot bigger than Jupiter.

So whats the difference between a planet and a moon?
A planet orbits the sun, and a moon orbits the planet.

(Well I hope I haven't gotten to boring yet!)
