Earth will get a second moon, but only for a couple of months. Here's everything you need to know about this cosmic phenomenon.

The space rock will make one complete orbit of our planet between Sept. 29 and Nov. 25 before escaping Earth's gravity. Yet despite this 57-day close flyby of our planet, the asteroid will be hard to spot as it's just 33 feet (10 meters) wide.

An asteroid is headed towards Earth. It's not going to hit us, but it is going to hang out for a couple of months. A recently discovered asteroid known as 2024 PT5 will fly into Earth's orbit, get caught there from Sept. 29-Nov. 25 and then eventually exit and continue its way through the solar system. Scientists call such phenomena mini-moons.

A small asteroid will be pulled into orbit around the Earth as a “ mini-moon ” later this month before the space rock departs into other parts of the solar system. The 10m-wide asteroid, dubbed 2024 PT5,

Earth is set to capture a new temporary moon for 53 days starting September 29. The small asteroid, 2024 PT5, will be caught by Earth's gravity and circle our planet before returning to space. Researchers describe this rare event as a "temporarily captured flyby" — an exciting celestial event to watch.
