Why does Haumea rotate so fast?
As Haumea orbits the Sun, it completes one rotation every 4 hours, making it one of the fastest rotating large objects in our solar system. It is possible a massive impact billions of years ago set off Haumea's spin and created its moons.
How did Haumea get its unusual shape?
Astronomers think that, in the early solar system, Haumea was much like Pluto, composed half of rock and half of water. Billions of years ago, a large object may have collided with the body, knocking most of the surface ice away and imparting a rapid spin to Haumea. The spin, in turn, elongated Haumea into its unusual shape.
Is Haumea a fast spinning planet?
Haumea: Fast-Spinning Dwarf Planet. Artist's concept of the dwarf planet Haumea and its two satellites (Hi’iaka and Namaka). Haumea is a dwarf planet that orbits the sun far beyond Neptune. It is about the same size as Pluto and has two moons. One of its notable characteristics is how fast it spins on its axis.
Why does Haumea have so many moons?

Why does Haumea rotate so fast?
Billions of years ago, a large object may have collided with the body, knocking most of the surface ice away and imparting a rapid spin to Haumea. The spin, in turn, elongated Haumea into its unusual shape. The moons of Haumea may have once been part of its surface, forming much like Earth's moon did after a collision.

every 4 hoursHaumea takes 285 Earth years to make one trip around the Sun. As Haumea orbits the Sun, it completes one rotation every 4 hours, making it one of the fastest rotating large objects in our solar system.
Why does Haumea have a ring?
Scientists think they formed from a collision between Haumea and another rocky body in the distant past. This collision would also account for Haumea's fast spin rate. It might also account for the rings. At one time, Saturn was the only body in the solar system known to have rings.

Orbit - Rotation Haumea's orbit has a high eccentricity and inclination. He rotates very fast, with a day lasting a mere 4 hours there. This probably accounts for his grey potato elongated shape.

What is Haumea made of?
Astronomers believe Haumea is made of rock with a coating of ice.
What is the fastest rotating object in our solar system?
Haumea is one of the fastest rotating large objects in our solar system. Its fast spin distorts Haumea's shape, making this dwarf planet look like a football.
What is the moon of Haumea?
Haumea has two known moons: Namaka is the inner moon, and Hi'iaka is the outer moon. Both are named for the mythological daughters of Huamea. Hi'aka is the patron goddess of the island of Hawaii and of hula dancers. Namaka is a water spirit in Hawaiian mythology.
Where is Haumea located?
Haumea Facts. Located in the Kuiper Belt beyond Neptune’s orbit, the dwarf planet Haumea is an oval-shaped object with a radius of about 385 miles (just under 10 times smaller than Earth), and two moons, Namaka and Hi’iaka.
How long is a day on Haumea?
A day on Haumea lasts only four Earth hours, making it one of the fastest rotating large objects in our solar system. Originally designated 2003 EL61 (and nicknamed Santa by one discovery team), Haumea resides in the Kuiper belt and is roughly the same size as Pluto.
Is Haumea cold?
Haumea is extremely cold and doesn't appear to have conditions suitable for life.
What would happen if Haumea spun faster?
A collision with some object that took place ages ago made Haumea spin really fast. It has by far the fastest spin and also the shortest day amongst any other object in the Solar System. If it spun any quicker, the planet would split itself in two.
What makes Haumea unique?
What makes Haumea so unique is its elongated, unusual shape, apart from your typical spherical dwarf planets – Ceres, Eris, Makemake, and Pluto.

Haumea is the third-largest dwarf planet in the Solar System, and it is quite far away from us, at 51 AU – one AU is the distance from the Earth to the Sun.
How long is a day on Haumea?
Haumea is one of the fastest rotating objects in the Solar System. Thus the days are very short – one day on the dwarf planet equals four hours on Earth. One year on Haumea is the equivalent of 285 Earth-years. This is how long it takes for Haumea to move around the Sun once.

Haumea's name comes from Hawaiian mythology – Haumea was the goddess of fertility and childbirth, also associated with "stone." She could transform herself from an older woman to a girl and passed on to humankind the ability to give birth naturally. Hi'aka and Namaka are her daughters. The first one is born from her mouth and the other one from her body.

What are some interesting facts about Haumea?
It has a strange shape, unusual brightness, two moons, and a wild rotation. Its unique features, however, can tell astronomers a lot about the formation of the solar system and the chaotic early years ...
Why is Haumea called Haumea?
IT'S NAMED FOR A HAWAIIAN GODDESS. In Hawaiian mythology, Haumea is the goddess of fertility and childbirth. The name was proposed by the astronomers at Caltech to honor the place where Haumea's moon was discovered: the Keck Observatory on Mauna Kea, Hawaii.
What does Haumea look like?
As a result of this tornadic rotation, Haumea has an odd shape; its speed compresses it so much that rather than taking a spherical, soccer ball shape, it is flattened and elongated into looking something like a rugby ball.
How big is Haumea?
Haumea is notable for the large amount of water ice on its surface, and for its size: Only Pluto and Eris are larger in the trans-Neptunian region, and Pluto only slightly, with a 1475-mile diameter versus Haumea's 1442-mile diameter. That means three Haumeas could fit sit by side in Earth—and yet it only has 1/1400th of the mass of our planet.
How do rings form on Haumea?
Ortiz says there are several mechanisms that can have led to rings around the dwarf planet: "One of our favorite scenarios has to do with collisions on Haumea, which can release material from the surface and send it to orbit." Part of the material that remains closer to Haumea can form a ring, and material further away can help form moons. "Because Haumea spins so quickly," Ortiz adds, "it is also possible that material is shed from the surface due to the centrifugal force, or maybe small collisions can trigger ejections of mass. This can also give rise to a ring and moons."
How old would you be if you lived on Haumea?
HAUMEA HAS ONE OF THE SHORTEST DAYS IN THE ENTIRE SOLAR SYSTEM. If you lived to be a year old on Haumea, you would be 284 years old back on Earth. And if you think a Haumean year is unusual, that's nothing next to the length of a Haumean day.
