Near-Earth asteroid is a fragment from the moon, say scientists

Spectrum of reflected light from Kamo`oalewa closely matches lunar rocks from Nasa's Apollo mission

Scientists have identified what appears to be a small chunk of the moon that is tracking the Earth's orbit around the Sun.

The asteroid, named Kamo`oalewa, was discovered in 2016 but until now relatively little has been known about it. New observations suggest it could be a fragment from the moon that was thrown into space by an ancient lunar collision.
