A visiting mini-moon is circling Earth, according to astronomers who discovered the cosmic squatter in our planet's orbit.
The tiny asteroid, dubbed 2020 CD3, was spotted by astronomers in Tucson, Arizona, on Feb. 15.
The discovery is a "big deal" because, out of roughly 1 million known space rocks, this is "just the second asteroid known to orbit Earth (after 2006 RH120, which was also discovered by the Catalina Sky Survey)."
Further observations and dynamical studies are strongly encouraged."
