Fact of the Day

A day on Jupiter is only 9 hours and 48 minutes long. Such fast rotation causes Jupiter to be somewhat squashed due to centrifugal force: its polar radius is 4000 km less than its equatorial radius (the latter being 71,392 km). That means you'd weigh almost 25% more at Jupiter's poles than at its equator, that is, if you could find a place to stand! So a 100 pound person (on Earth) would weigh 230 pounds at Jupiter's equator but 285 pounds at the pole!
