Report According to, for many years scientists had believed that the crater on the Moon was caused by the impact of an asteroid and that asteroid had come into our solar system from outside. In 2016, scientists discovered a mysterious rocky piece which is revolving around the Sun. Its diameter ranges between 130 to 328 feet. That rock was named Kamoʻoalewa.
Now a research team from Tsinghua University led by astronomer Yifei Jiao has said that the rock was part of the Moon millions of years ago. Due to its rupture from the Moon, a crater named Giordano Bruno crater was formed on the Moon, which is 22 kilometers across. Giordano Bruno was named after a 16th-century Italian cosmologist.
Scientists say that an asteroid named Kamoleva, 131 to 328 feet wide, separated from the Moon about 10 million years ago. Because of that the Giordano Bruno crater was formed. This study has been published in Nature Astronomy Journal.
This study is important because a rock got separated from the moon and a crater was formed there. The same rock has now become an asteroid and is revolving around the Sun. Scientists have not yet been able to explain in detail why the asteroid-like rock got separated from the Moon.
