(CNN) It's not the moon, but you can call it mini-moon.

Earth has captured a tiny object and pulled it into orbit.

The asteroid, known as 2020 CD3, is only the second asteroid known to orbit Earth. And while it won't last, this asteroid acts as a temporary mini-moon whirling around our planet. The asteroid is expected to drop out of orbit around the Earth in April and return to a heliocentric orbit, which is an orbit around the sun.

The International Gemini Observatory captured this image of 2020 CD3 at the center using the 8-meter Gemini North telescope on Hawaii's Maunakea.

The discovery was made by Kacper Wierzchos and Theodore Pruyne, researcher specialists for the Catalina Sky Survey. It's a NASA-funded project at the University of Arizona's Lunar and Planetary Laboratory in Tuscon, Arizona.

The survey is supported by the Near-Earth Object Observations Program, which reports into NASA's Planetary Defense Coordination Office. Specialists at Catalina help NASA discover and track near-Earth objects that could be potentially hazardous to the planet.
