Earth’s Quasi-Satellite Kamooalewa Could Be Fragment of the Moon

Could Be Fragment of the Moon
Nov 12, 2021 by Natali Anderson

Using the Large Binocular Telescope and the Lowell Discovery Telescope, astronomers have conducted a comprehensive physical characterization of the near-Earth asteroid (469219) Kamo’oalewa and assessed its affinity with other groups of near-Earth objects (NEOs). They’ve found that Kamo’oalewa’s spectrum matches lunar rocks from NASA’s Apollo missions, suggesting it originated from the Moon. An artist’s impression of Kamo’oalewa near...
