Earth to Have 57-Day 'Second Mini Moon' From Sept. 29

The Facts

• 2024 PT5, a 33-ft long asteroid discovered in August, is reportedly set to make a “horseshoe path” around Earth, turning into its second moon from Sept. 29 to Nov. 25.

• Temporarily captured by Earth's gravity, 2024 PT5 reportedly belongs to the Arjuna asteroid belt and won't be visible to most stargazers given its small size.

• 2024 PT5 is reportedly among those asteroids of the Arjuna belt that become more affected by Earth’s gravity than is usual because they move relatively slowly.
