A world spinning so fast that it has stretched into the shape of an egg.
Haumea spins once in about 3.9 hours, one of the fastest rotations of any large body in the solar system. The fast spin stretches it into an elongated shape.
In 2017 astronomers watching it pass in front of a star discovered that it has a ring. It has two known moons, Hiʻiaka and Namaka.
