This animation depicts the trajectory of 2020 CD3 from January 2019 to July 2020. The moon might escape from earth's orbit in April. The image combines three images each obtained using different filters to produce this color composite.

“It is heading away from the Earth-moon system as we speak,” New Scientist quoted Grigori Fedorets at Queen’s University Belfast in the UK, as saying.

The object has been orbiting Earth for at least a year and probably more, presumably after being captured by the Earth’s gravity from an orbit about the Sun.
Below we provide Asteroid 2020 CD3 (Earth's minimoon) finder charts showing where the object is right now in the sky with respect to the brightest stars.
The first finder chart has a field of view of 50 degrees, while the second one has a field of view of 10 degrees. So what are you waiting for? Representative Image/Getty. Space experts in particular wish to understand how bright 2020 CD3 is shining and how much light it reflects. Images of the new moon were captured on February 15 Earlier this week, the scientific community was abuzz when astronomers found space rock "2020 CD3" has actually been circling Earth for three years. International Gemini Observatory image of 2020 CD3 (center, point source) obtained with the 8-meter Gemini North telescope on Hawaii’s Maunakea. 2020 CD3 remains stationary in the image since it was being tracked by the telescope as it appears to move relative to the background stars, which appear trailed due to the object’s motion. "Obtaining the images was a scramble for the Gemini team because the object is quickly becoming fainter as it moves away from Earth," explains Gemini Observatory astronomer John Blakeslee, adding that the new celestial superstar 2020 CD3 is expected to leave us forever some time in April. The orbit of 2020 CD3 isn’t stable, so it will eventually be thrown away from Earth. Astronomers hope to obtain more images of the object to learn more about it.
