Astronomers say Earth may have a new microsatellite

Astronomers from NASA-funded the Catalina Sky Survey project believe they have discovered an asteroid that has caught the earth’s gravity,media CNET reported. Astronomer Kacper Wierzchos tweeted Tuesday: “The Earth has a new temporary capture object/possible mini-satellite called 2020CD3.

Wierzchos calculates that the asteroid is between 1.9 and 3.5 meters in diameter. The Asteroid Center has identified this near-Earth object, which apparently entered Earth’s orbit about three years ago. The Catalina Sky Survey project is based on the Moon and Planetary Laboratory in Tucson, Arizona.

This is the second asteroid to enter Earth’s orbit. Science writer Corey S. Powell points out that the Catalina Sky Survey team had previously discovered an asteroid called 2006 RH120 that orbited the Earth for 18 months between 2006 and 2007.
