Haumea
Dwarf Planet
Haumea spins so fast, once every four hours, that it has been stretched into an elongated oval shape like a rugby ball. It orbits beyond Neptune and even has its own faint ring system and two known moons.
Field Notes
- Haumea completes a full rotation in under 4 hours, making it one of the fastest-spinning large bodies in the solar system.
- That rapid spin has physically stretched it into an elongated, egg-like shape.
- It has a thin ring system, discovered in 2017 — a rarity among small solar system bodies.
