The Earth has temporarily captured a new mini-moon which is between the size of a cow and a hippopotamus.

The moon is an asteroid that is called 2020 CD3 that has a diameter between 1.9 – 3.5m

The new moon that is temporarily bound to Earth was discovered on Tuesday by the International Astronomical Union’s Minor Planet Centre. The organisation is responsible for the designation of minor bodies in the solar system.

The astronomers Kacper Wierzchos and Theodore Prune working at the Catalina Sky Survey in Arizona, US had first detected the asteroid on February 15.

BIG NEWS (thread 1/3). Earth has a new temporarily captured object/Possible mini-moon called 2020 CD3. On the night of Feb. 15, my Catalina Sky Survey teammate Teddy Pruyne and I found a 20th magnitude object. Here are the discovery images. pic.twitter.com/zLkXyGAkZl

In a tweet, Weirzchos described the discovery as “big news”.

“Earth has a new temporarily captured object/Possible mini-moon called 2020 CD3. On the night of Feb. 15, my Catalina Sky Survey teammate Teddy Pruyne and I found a 20th magnitude object. Here are the discovery images,” he tweeted.

(3/3) The object has a diameter between 1.9 – 3.5 m assuming a C-type asteroid albedo. But it’s a big deal as out of ~ 1 million known asteroids, this is just the second asteroid known to orbit Earth (after 2006 RH120, which was also discovered by the Catalina Sky Survey).

He further said that it was a big deal because out of ~ 1 million known asteroids, this was just the second asteroid known to orbit Earth.

The first one was 2006 RH120, which was also discovered by the Catalina Sky Survey.

The mini-moons are pulled into the Earth’s orbit due to the Earth’s, the moon’s, and the sun’s gravity at the same time, which produces irregular orbits.

(2/3) The object has just been announced by the MPC and its orbit shows that it entered Earth’s orbit some three years ago. Here is a diagram of the orbit created with the orbit simulator written by Tony Dunn: pic.twitter.com/2wsJGtexiO

The astronomer has estimated that the ‘mini-moon’ entered Earth’s orbit some three years ago.

Meanwhile, the mini-moon is likely to stick around the Earth from October 2020 to May 2021. Within this period, the heavenly body is expected to edge closer to us, which will give us the chance to make more detailed observations and settle the matter of its origin for good, reported metinfo.net
