According to astronomers who saw this object orbiting our planet, the Earth attained the second "mini-moon" about the size of a car.
NASA-funded Catalina Sky Survey in Arizona on the night of February 15, researchers Kacper Wierzchos and Teddy Pruyne observed that its mass - about 1.5 to 1.5 meters (-11-1 ft) in diameter.
"This is a big news. Earth has a new temporarily captured object / possibly mini-moon it's called 2020 CD3," possibly a C-type asteroid, Wierzchos tweeted on Wednesday.
It was a "big deal" as "this is just the second asteroid known to orbit Earth (after 2006 RH120, which was also discovered by the Catalina Sky Survey)," says the astronomer.
He also said, Its route to offer it entered Earth's orbit three years ago.
"No link to a known artificial object has been found," implying it was likely an asteroid captured by Earth's gravity.
The Smithsonian Astrophysical Observatory's Minor Planet Center, which collects data on minor planets and asteroids, said in an announcement.
"Orbit integrations reveal that this object is temporarily tied to the Earth."
The car-sized object was not the Tesla Roadster he inaugurated into space in 2018, which is now circling the Sun, said Tech entrepreneur Elon Musk. He tweeted, "It's not mine."
