The asteroid’s unusual shape could be formed under the influence of tidal forces. Some scientists believed that it could be created artificially by extraterrestrial civilization.
Astronomers from USA and China revealed the secret of the emergence of alien probe – interstellar asteroid Omwamwi. It is reported by the scientific journal Nature Astronomy.
Specialist conducted a computer simulation and found a possible explanation for the unusual shape of the cosmic body.
Omwamwi the asteroid has an elongated shape and not surrounded by the usual space bodies such vague shell. Because of this, some scholars believed that it could be created artificially by extraterrestrial civilization.
According to the study, these asteroids can be produced by fragmentation of parent bodies held too close to the stars. Their fragments are ejected into interstellar space, and the surface of the asteroid will melt.
This crust will provide the asteroid structural stability of an elongated shape. Tidal destruction also reduces the amount of volatile substances, which explains the color of the surface Omwamwi and lack around him the vague shell.
Yesterday it was reported that for the finest pictures of the Sun found a mysterious thread. Also the Correspondent wrote that zipping near Earth asteroid can be seen.
