Get ready for a cosmic surprise this autumn - Earth is about to get a second moon, according to scientists.

A small asteroid is going to be captured by Earth’s gravitational pull and temporarily become a "mini-moon".

This space visitor will be around from September 29 for a couple of months before escaping from Earth's gravity again.

Sadly the second moon is going to be too small and dim to be seen, unless you have a professional telescope.

The asteroid was first spotted by NASA’s Asteroid Terrestrial-Impact Last Alert System (ATLAS) on 7 August.

Scientists worked out its trajectory in a study published, external in Research Notes of the American Astronomical Society.

The asteroid, which scientists refer to as 2024 PT5, hails from the Arjuna asteroid belt, which contains rocks that follow an orbit quite similar to Earth’s.
