(CNN) — Earth is about to gain a new “mini-moon,” but it won’t stay around for long. The newly discovered asteroid, named 2024 PT5, will temporarily be captured by Earth’s gravity and orbit our world from Sept. 29 to Nov. 25, according to astronomers. Then, the space rock will return to a heliocentric orbit, which is an orbit around the sun.

For nearly two months this year, Earth’s moon will have company — a second moon. Technically, it isn’t a second moon, but rather an asteroid from the Arjuna asteroid belt — named 2024 PT5 — that will be caught in the Earth’s gravitational pull,

Here’s what to know about our new, temporary celestial neighbor. Earth has a large gravitational pull. So it’s not uncommon for objects flying through space to be attracted to it or get caught up in an orbit — at which point they earn status as miniature moons. The same happens with objects purposefully placed in space, such as satellites.
