Earth to have a two-month mini-moon from September 29 until November 25 

Earth can regularly capture asteroids and pull them into our orbit making them mini-moons. 

Asteroid 2024 PT₅ was discovered this year, is about ~33 feet/ 10 meters wide, and follows a path similar to that of Earth’s mini-moon from 2022. 

Asteroid 2024 PT₅ will be too small to see with binoculars or with home telescopes.

Data shows that 2024 PT₅ will become a mini-moon of Earth on 2024 September 29 (20:02), and will return to its normal path 56.6 days later, on November 25 (10:33). 

It will then leave the vicinity of Earth in January of 2025 and will likely return in 2055. 

This has happened before. Other examples of an object being temporarily captured in the Earth’s orbit are:

• 2006 RH₁₂₀ that remained gravitationally bound to Earth from July 2006 to July 2007
• 2020 CD₃ that escaped early in 2020 May after being bound to Earth for several years
• 1991 VG was briefly captured in February 1992 
• 2022 NX₁ was a short-lived mini-moon of Earth in 1981, 2022, and it will return as such in 2051
