Scientists have figured out where one of the strangest objects in the solar system came from

This object is an unusual, rapidly rotating dwarf planet called Haumea.

Related video < p>One of the most unusual objects at the edge of the solar system is the dwarf planet Haumea. It was discovered only in 2004, it has a diameter of about 100 km, makes a full revolution around the Sun in 284 years, but the strangest thing is its period of rotation around its axis. Haumea is the fastest rotating object in the solar system. The dwarf planet makes a complete rotation around its axis, that is, 1 day passes on it, in 4 Earth hours. Scientists from NASA may have figured out how this strange planet appeared, writes Space.

Ellipsoid in the Kuiper belt

Haumea is located in the Kuiper belt, which is a region of space at the edge of the solar system, which consists of ice rocks and comets, as well as other trans-Neptunian objects, because this belt is located beyond the orbit of Neptune. This, we recall, is the eighth and most distant planet of our solar system.

Due to its very fast rotation, Haumea is not spherical like the dwarf planet Pluto (which only 16 years ago ceased to be the ninth planet in the solar system). It resembles a rugby ball in shape, that is, it has the shape of an ellipse.

The Haumea Family

But not only this distinguishes the dwarf planet from other objects in the Kuiper belt. Haumea's surface is mostly water ice, unlike most other bodies at the edge of the solar system. Ice objects close to the dwarf planet that move in the same orbit have the same surface. Scientists decided that they all have the same origin and constitute a single family of similar objects – the Haumea family.

NASA scientists used computer simulations to figure out how such an unusual object as Haumea and its “relatives”. This planet is so far away that it is rather difficult to make accurate calculations of its characteristics with existing telescopes.

“In our simulations, we fed the necessary data that we already know: the approximate size of the planet, the approximate mass, and also that it has such a fast rotation speed. Using this information, we were able to figure out how the mass of the dwarf planet is distributed and how this distribution affects its rotation. You need to understand the essence of this planet before delving into its history, “says Jessica Noviello of NASA.

Study results

Simulation results showed that at the beginning of its history, Haumea was 3% larger than it is now, and this difference explains the appearance of “relatives” of the dwarf planet. The scientists also found that most likely Haumea originally rotated at a different speed and its volume was larger than now.

The simulations also showed that in the early years of its existence, at the very beginning of the history of the solar system, Haumea collided with another body. This led to the fact that pieces broke off from the dwarf planet. But they did not become those ice objects that are next to the owner, because such a strong impact would have thrown the debris much further into space.

Scientists believe that the objects surrounding Haumea most likely formed later, when the dwarf planet actively evolved. The gradually increasing speed of its rotation led to the fact that pieces of ice began to fly away from its surface, which became part of the Haumea family.

To date, scientists know that the dwarf planet Haumea has 2 satellites, Hiiaka and Namak, as well as a system of rings.

As for the outer part of the solar system, as Focus already wrote, scientists have made an important discovery that concerns the shell that envelops our star system called the geoliosphere . In particular, they determined the presence of strange processes that occur on the border between the geolisphere and interstellar space.
