One of the international efforts to find asteroids that could hit the Earth in 2016 was the discovery of the asteroid Kamoa’aleva. (Kamo’oalewa) in diameter of 40-100 meters. And it spins pretty fast for asteroid status.

Recently, a small team of international planetary scientists A report in the journal Nature Astronomy shows evidence supporting the theory that the asteroid Kamoa’aleva ejected from the moon. The latter made an extensive study of asteroids and possible places on the moon. Where the Asteroid Kamoa’Aleva comes from The team created a computer model to simulate the collision. That could lead to a piece of the moon’s surface the size of the asteroid Kamoa Aleva being thrown out into space. So that the team was able to estimate the size of another asteroid that would hit the moon. After that, the size of the cracks that are left behind will occur.

Scientists also noted that the accident must have happened recently. The team also compared samples of lunar material brought back to Earth. A striking similarity was found between samples from the Giordano Bruno crater and the asteroid Camooaleva, both of which also contain the mineral pyroxene.
