Moon Rocks Blasted Off Lunar Surface Could Be Near-Earth Asteroids

Astronomers have discovered that the asteroid Kamo'oalewa, which orbits within 9 million miles of Earth every April, is likely a chunk of the moon. A new study suggests that an ancient asteroid impact could have propelled the rock onto its current trajectory and indicates the possibility of more moon fragments in the solar system. The asteroid's unusual orbit and composition, similar to the moon's, led scientists to investigate further. By simulating asteroid impacts on the moon, researchers found that some rocks could end up in near-Earth orbits, providing insights into hazardous near-Earth asteroids. Further research will focus on determining the conditions and timing of the impact.
