Near-Earth Asteroid Likely Came from Moon

NASA: Near-Earth Asteroid Likely Came from the Moon
Last year, astronomers on the hunt for potentially dangerous near-Earth asteroids spotted something unusual. A space rock, now dubbed 2024 PT5 made several close passes by Earth, not quite orbiting our planet,
Earth's recent asteroid visitor might've been a piece of the moon
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.
Study finds that Earth's small asteroid visitor is likely a chunk of moon rock
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.
A piece of the moon? Small asteroid may be a lunar rock ejected by impact
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.
Chunk of Moon Rock? NASA Tracks Asteroid 2024 PT5 During Close Earth Flyby
NASA’s Goldstone Solar System Radar is closely tracking asteroid 2024 PT5 during its nearest approach to Earth, a distance still five times farther than the Moon. First spotted in August 2024 by the University of Hawaiʻi’s ATLAS telescope,
Earth’s Mini-Moon Was Probably a Piece of Its Real Moon
Scientists think a small rock discovered near Earth last August was hurled into space by an ancient impact on the lunar surface.
