Taking a closer look at the new mini-moon, astronomers have learned more about its origin. On August 7, astronomers discovered a new near-Earth object, dubbed 2024 PT5. Analyzing the object, around 10 meters (33 feet) in diameter, astronomers from the Complutense University of Madrid, Carlos de la Fuente Marcos and Raúl de la Fuente Marcos, found that it was on a pleasing trajectory.
