According to the researchers, the tail appeared after a collision with another celestial body.
Astronomers from the ATLAS project found that one of the Main-belt asteroids, 6478 Gault, has a tail, whose length is about 400 thousand kilometres. According to the researchers, the tail appeared after a collision with another asteroid, which occurred about two months ago.
The asteroid was discovered in 1988, husband and wife, the shoemaker and named in honor of geologist Donald Gault, known thanks to the research of the formation process of craters on the moon, Mars and other planets. Asteroid Galt belongs to the Phocaea family, which consists of about two thousand asteroids that occurred 2.2 billion years ago. The average diameter of the asteroid is 3.7 kilometers.
In early January, scientists who observed the asteroid, I noticed the appearance of a celestial body’s tail. Gas and dust tails – a mandatory attribute of comets, they consist mainly of volatile substances, frozen water and gas, which starts to evaporate when approaching the Sun and drawn out into a tail. For asteroids this decoration is very unusual because they are composed mainly of rock.
According to the researchers, the tail of the Galt was the result of a collision with another asteroid, which occurred in late October – early November 2018.
Previously, the station “Hayabusa-2” is transmitted to Earth new images of the asteroid Ryugu.The images are visible of a group of boulders and large rock in the Northern polar region of the asteroid. It is noted that the camera took pictures of from 18 to 20 June, being at a distance 200-100 km from the surface of a celestial body.
