Do you get dizzy riding a child’s merry-go-round? If so, don’t visit Beta Pictoris b. About 3,000 times bigger than our planet, it spins so fast on its axis that one day on its surface lasts only 8 Earth hours.

On April 30, astronomers announced in the journal Nature that, for the first time, they’ve measured the spin of a planet outside our solar system. The exoplanet in question is called Beta Pictoris b, a large gas planet located a relatively close 63 light years from Earth.
