Yet a new study reveals that for the next two months, 2024 PT5 will join our Moon in orbit around our planet, which means Earth will (temporarily) have a second moon, from September 29 to November 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.
