Earth bids farewell to 'mini moon' asteroid set for return visit in 2055
Earth is bidding farewell to a "mini moon" asteroid that has been orbiting the planet for the past two months. The asteroid, which poses no threat to Earth, is set to leave on Monday and is expected to return in 2055. The asteroid, designated 2020 CD3, is estimated to be around 6-12 feet (1.9-3.6 meters) in diameter and has been in a temporary orbit around Earth since it was first detected in February 2020. This type of temporary satellite, known as a "mini moon," is a rare occurrence, with only a handful of such objects being identified in the past. Despite its small size, the asteroid's departure is being closely monitored by astronomers, who are interested in studying the dynamics of these temporary celestial companions. The 2020 CD3 asteroid is expected to continue its journey around the Sun, and its return in 2055 will provide an opportunity for further observation and research.
