It won't be there forever, but Earth will have a second moon when a small asteroid begins to orbit the planet later this month, space researchers have announced.

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.

The asteroid is expected to make a “horseshoe path” around Earth over the next two months. For the next two months, an unusual object about the size of a bus will be orbiting above our heads. Say hello to Earth’s temporary new moon.
