Astronomers have traced the origin of asteroid 2024 YR4, which appears to have broken off from a larger space rock.

The once-dubbed "city-killer" asteroid 2024 YR4 has surprised scientists with its 'unusual' shape as it rapidly rotates through space on a trajectory that could see it hit the moon.

A “city-killer” space rock headed for a potential collision with the Moon likely originated in the asteroid belt near Jupiter, a region not known to produce Earth -crossing asteroids, according to a new study.
