Favorite Planet/Moon

My favorite planet is Jupiter because it is the fastest spinning planet in the solar system even though is massive. It takes Jupiter 10 hours to complete one full rotation on its axis. It's red spot has been around for 350 years and is measured 4o,ooo km across Jupiter but is shrinking as well. Scientist don't know when it will disappear. Jupiter also had 63 moons orbiting around it right now.
