Earth's "quasi-moon" was likely blasted away from the actual moon relatively recently in the solar system's history, a new study suggests.
Kamo'oalewa, a 131- to 328-foot-wide (40 to 100 meters) near-Earth object (NEO), was liberated by an asteroid impact between 1 million and 10 million years ago, a smashup that created the moon's 13.7-mile-wide (22 kilometers) Giordano Bruno crater, according to the research.
