An Arjuna asteroid, discovered in August, will become a "mini-moon" event for nearly two months from Sept. 29 to Nov. 25.

Though the mini-moon will only be in Earth’s orbit for about two months, it’ll stay close to the planet for a few months, making its closest approach in January 2025, after which it’s expected to make a return to the planet’s orbit in 2055, according to the study.

A newly discovered asteroid, also referred to as a mini-moon or second moon, is set to enter Earth's orbit temporarily this fall.
