For just a few months, Earth hosted a "second moon," much smaller than our faithful historical companion. This fleeting phenomenon, known as 2024 PT5, captivated astronomers before departing

The idea that Earth has only one moon is considered to be true, but that isn't always the case. In fact, sometimes, it's had more moons than you'd expect.

Earth's recent "mini-moon" asteroid 2024 PT5 didn't stick around for Thanksgiving, but don't be sad. It will be back... but will it ever be a second moon again?

Earth will say goodbye to an asteroid that has acted as a mini moon for the past two months. But astronomers say it will return again soon.

A temporary “mini- moon ” orbiting the Earth for the last two months drifted away on Tuesday, resuming its journey around the Sun. The 10m-wide asteroid dubbed 2024 PT5 had been circling the Earth since 29 September in an orbit about 3.2 million km from the planet.
