There may be more moon-born asteroids near Earth than we think
ESA/P.Caryl
The giant rock orbiting near Earth appears to have originated from the moon, and is only the second such object known to exist, with perhaps a dozen more awaiting discovery.
The asteroid, called 2024 PT5, is about 10 meters wide. It was discovered in August, but was then captured by Earth’s gravitational pull and became Earth’s second satellite, known as a minimoon, between September and November.
