2024 PT5 is the second near-Earth asteroid scientists suspect was ejected from the moon's surface, the first being 469219 Kamo'oalewa, which a different team of scientists have traced to an old impact crater on the far side of the moon.

The asteroid is about 33 feet (10 meters) across and poses no danger to Earth. It joins another known lunar asteroid discovered in 2016 known as 469219 Kamo’oalewa. Scientists hope that as telescopes become more powerful, we will be able to detect more bits of the Moon that have been blasted free in ancient impacts.

A near-Earth object was likely ejected into space after an impact thousands of years ago. Now it could contribute new insights to asteroid and lunar science.

The sun’s light exerts a tiny force called “solar radiation pressure” on objects in space. Lightweight human-made debris, like hollow rocket parts, gets pushed around more easily, like a tin can in the wind. Natural objects like asteroids are much denser and less affected.

Typically, asteroids - like the one depicted in this artist's concept - originate from the main asteroid belt between the orbits of Mars

PT5, initially believed to be a tiny asteroid, likely originated from the Moon. Discovered in 2024, PT5's reflectance and composition closely match lu
