Earth has a new moon, but you probably won't notice it

About three years ago, an object called Astronomer 2020 CD3 was a common asteroid that wandered through the vastness of the vast universe. After the stone made of carbon rock had conquered the earth's gravity network, it turned into an earth satellite, which due to its size is now considered to be our "Miniloon". The discovery of the tiny moon was announced by astronomers from the Catalina Sky Survey, who observed the movement of a stone near our planet's orbit on the night of February 15, 2020.

A new satellite has been discovered in orbit

New Earth Satellite

A small piece of stone with a diameter between 1.9 and 3.5 meters is just one of the million asteroids that fly near our planet every year. About 3 years ago, a fragment of fate landed in close proximity to our planet, but instead of crashing to Earth, the asteroid chose a different fate and became one of the blue planet's temporary moons, sciencealert.com reports.

As of February 27, there will be 22,211 asteroids of various sizes near Earth's space. However, due to the fact that they are all small, they can only be seen with relatively large telescopes. You might think that with a small mass of stones flying around the Earth, all of them are absorbed by Earth's gravity. In fact, this happens, though most "space tourists" don't stay in orbit long enough to become our real miniluns.

Part of the captured cosmic stones go directly into the earth's atmosphere, where they cease to exist and turn into spectacular fireballs. The other part glides along the orbit of the planet until speed takes it to the depths of the universe.

Due to the fact that "miniluns" are very difficult to recognize in the entire history of observation, scientists had only a few candidates for miniature earth satellites. One of the officially confirmed objects was an asteroid called the 2006 RH120, which revolved around the earth from 2006 to 2007. An object that regularly falls under the influence of a geocentric orbit becomes the satellite of our planet every 20 years. Then it flies again near the sun.

However, the presence of small temporary satellites on Earth is of great importance for modern science. Both the CD1 RH120 and CD3 2020 offer mankind the unique opportunity to study asteroids without crossing the environment of our planet.

Sending spacecraft to asteroids is a fairly expensive and time-consuming task. Due to the large distances between humans and space debris, studying asteroids is often not possible. "Miniluns" violate this rule, which is not very pleasant for science. So small satellites can help analyze the surface structure of distant objects and also provide an answer to how asteroids are captured by the earth, which will make it much easier for specialists to find similar stones in the future. In any case, astronomers do not have much time left: According to preliminary modeling, CD3 will leave Earth's orbit by April 2020.
