Dwarf planet lesson

Haumea

Dwarf planet

Haumea is a fast-spinning dwarf planet in the Kuiper Belt. Its rotation stretches it into an oval shape.

Kid fact

Haumea spins so fast that a day there is only about four hours.

Fast spinner

Haumea rotates quickly, completing one spin in about four hours. That fast spin helps stretch it into an oval-like shape.

Kuiper Belt home

Haumea orbits in the Kuiper Belt, where sunlight is weak and many objects are made of rock mixed with ice.

Moons and ring

Haumea has two known moons and evidence of a ring. That makes it a surprising small system far beyond Neptune.

Why images are hard

Haumea is so distant and small that telescopes cannot easily show surface details, so learning images often use artist concepts.

Look closely

Focus on the stretched shape, the possible ring, and the idea that spinning can change how a world looks.
