Astronomers Queens University in Belfast found that Omwamwi interstellar asteroid, nicknamed “the spaceship”, chaotically rotating. According to the findings of researchers, the anomaly caused by a collision with another space object. About it reported in a press release on Phys.org.
The researchers analyzed measurements of the brightness of the asteroid and found that Omama has no stable axis of rotation as the other small Solar system objects. Simulations showed that the anomalous behavior of the heavenly bodies will continue for billions of years before it will again begin to rotate normally due to the effects of internal tension. The volatility of the axis due to a collision with another asteroid, which threw Omwamwi from their native planetary systems in interstellar space.
Omwamwi is the first interstellar object, which was able to detect the person. The cigar-shaped asteroid reaches a length of 400 metres and a diameter of about 30 meters. The object was discovered 19 October 2017 at a distance of 0.2 astronomical units from Earth.
Scientists project Breakthrough Listen made that interstellar Omwamwi object could be alien ship.
