Earth will get another moon this month  — but not for long!

A blue-and-green planet dotted with white clouds next to a lumpy space rock and a grey-and-white moon pockmarked with craters.

This month, Earth will grab itself a second moon in the form of the tiny asteroid 2024 PT5. 

Unlike the moon, Earth's primary companion which has accompanied our planet for around 4 billion years, this "new mini-moon" will stick around for just two months before it heads back to its home in an asteroid belt trailing our planet and orbiting the sun.
