Jumpin’ Jupiter

In our solar system, Jupiter (the 5th planet from the Sun) is the fastest spinning planet. Jupiter’s equator rotates at 28,273 miles an hour. Which means on average it completes one full rotation in under 10 hours!

Pretty fast considering its size. Jupiter is the largest planet in our Solar System, with a mass that is literally two and one half times that of all other planets in our Solar System combined!

Venus spins slowest at about 4.05 miles per hour, while here on Earth we are spinning along at about 1,037.6 miles an hour.  It takes Venus about 243 of our Earth days to complete one full rotation.
