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.

New research suggests that Earth's recent mini-moon might have originated as part of our actual moon long, long ago.

PT5, initially identified as a near-Earth asteroid, is believed to be a lunar fragment due to its unique orbit and mineral composition matching l

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.

The study suggests that the Moon likely formed largely from Earth's mantle material — with minimal involvement from Theia.
