SOLAR SYSTEM

Detailed explanation-1: -Haumea 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.

Detailed explanation-2: -Sometime early in its history, another large Kuiper belt object collided with Haumea obliquely. This collision knocked away most of the ice (which would have been on the outside) of Haumea, leaving just a rock covered in a thin film of ice. The oblique impact caused Haumea to spin rapidly.

Detailed explanation-3: -A violent formation 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.

Detailed explanation-4: -Water soaked into the rocky material at the center of Haumea and made it swell into a large core made of clay, which is less dense than rock. The larger core increased the moment of inertia and thus slowed Haumea’s spin to its current rate.

Detailed explanation-5: -Haumea is the most distant solar system body with a ring and the only dwarf planet and Kuiper belt object to have one.

Detailed explanation-6: -Following the discovery of Eris (an even larger object on the edge of the Solar System), a new classification of ‘dwarf planet’ was introduced and its current membership includes Ceres, the largest asteroid, Pluto and Eris and the two that have been added since the classification was created: Haumea and Makemake.
