Comet Oumuamua may be a fragment of the planet: the secrets of the first guest of the solar system

The interstellar object Comet Oumuamua may be part of the planet. This conclusion was reached by astronomers. They created a simulation of the comet's movement and arrived at a history of its origin. According to the researchers, the comet could be part of a huge planet. Having broken away as a result of a collision with some cosmic body, Oumuamua began an independent movement, becoming a guest of the solar system in 2017.

Simulation and study of the history of the comet suggest that the planet, a fragment of which became Oumuamua, could be torn apart by the gravity of its star. From the moment the comet first appeared in the Solar System in 2017, astronomers are trying to determine its origin.


There were various versions, including the assumption that Oumuamua is an asteroid from another galaxy, part of an exploding star, an alien ship. University of California astronomers created a computer model and found that if a comet was part of a planet, then this planet could be very close to its parent star.

They could move very close to each other in a radius of about 600 thousand kilometres. It is almost 80 times closer than the distance from Mercury to the Sun. In such situations, star gravity acts mercilessly. She tears nearby objects and scatters them around interstellar space. If a comet is indeed fragments of an exploding star, then its forms have a logical explanation.

And astronomers understand why the speed of its movement became so high that it ended up in the solar system. The simulation showed that a fragment of the planet may have a cigar-shaped shape. Oumuamua has the same shape.


The computer model assumes that a dense layer of ice is located inside a fragment of the planet. Water vapour could form in it since the comet was heated by the Sun. Astronomers call the calculations of the state of the comet convincing, they explain the strange properties of the interstellar guest, which can give new knowledge about the formation of planets in other galaxies. Astronomers predict its future fate: the comet will fall apart.
