An asteroid that orbited near Earth for a few months as a mini-moon may be a chunk of the moon that was blasted off by an impact thousands of years ago.

The small near-Earth asteroid 2024 PT5 has been creating a buzz among researchers. Discovered last year with the help of a NASA-funded telescope, it is only about 33 feet across and does not pose any threat to Earth.

A chunk of space rock that visited near Earth's orbit last year was widely called a "mini-moon," a nickname that was more appropriate than thought.
