NASA revealed the origins of Homei, the most mysterious planet in the solar system

NASA researchers believe that the strange shape and unusual composition of the mysterious dwarf planet, Homei, is linked to an ancient collision, and the results of computer simulations are published in The Planetary Science Journal.

Homea is a dwarf planet in the Coyper Belt, just as small as Pluto. It spins around its axis extremely quickly for such a massive object, the "day" only lasts four hours. Because of the high speed of rotation, the planets are not like a ball, but rather like a folded ball for American football.

But it's not the only weird thing: Homei's surface, which is mostly composed of water ice, is almost no other surface in Coyper's belt, except for a group of asteroids that travel in similar orbits and are believed by scientists to be connected to a planet of shared history.

Researchers used computer simulations to understand how such a strange planet could be formed. For their calculations, scientists used only established data: the size and mass of Homea and its short four-hour "day".

By modelling, scientists have restored the total density of the planet and its core, the amount of ice on the surface of the planet, and the distribution of the mass that affects its rotation.

Based on their simulations, scientists have made the hypothesis that when the planets were formed, Homea faced another object, and not the fragments of that explosion formed the planet's "satellites" and they were abandoned to distant orbits and lost contact with it over the years of evolution.

The "family" of the planet was formed much later, scientists believe. In the formation of the planet, dense rocky material settled in the center, while lighter ice rose to the surface, and the planet itself was spinning faster than it was today.

At the same time, the planet ' s radioactive rock produced heat that melted part of the ice, creating the ocean beneath the surface, so the water absorbed the rocky material in the center of Homea and forced it to fill a large core of clay that was less dense than the rock, and the growth of the core had slowed the planet ' s rotation to the current speed.
