Earth’s Second Known Minimoon is Natural Object, Astronomers Say

This image, taken with the 8-m Gemini North telescope on Hawaii’s Maunakea, shows Earth’s minimoon 2020 CD3 (center, point source). The image combines three images each obtained using different filters to produce this color composite. Image credit: International Gemini Observatory / NOIRLab / NSF / AURA / G. Fedorets.

In a new paper published in the Astronomical Journal, astronomers from the United States, Canada and Europe provide a detailed characterization of the physical properties and orbital evolution of the asteroid 2020 CD3 — Earth’s second discovered temporary natural satellite, or minimoon. Their results prove that 2020 CD3 is a natural body and not some relic piece of human-made space junk. This image, taken with the 8-m Gemini North telescope...
