Earth Captures Temporary 'Mini-Moon' 2024 PT5

The newly discovered asteroid will orbit Earth for 57 days before returning to its path around the sun.

  • 2024 PT5 is a near-Earth asteroid about the size of a school bus, measuring approximately 33 feet wide.
  • The mini-moon was captured by Earth's gravity on September 29 and is expected to remain in orbit until November 25.
  • Despite its intriguing nature, 2024 PT5 is too small and dim to be seen with the naked eye or typical amateur telescopes.
  • Originating from the Arjuna asteroid belt, the asteroid is predicted to make another close approach to Earth in January 2025.
  • This is not Earth's first temporary satellite; previous mini-moons have included 2006 RH120 and 2020 CD3.
