Two Russian observatories recorded the asteroid 2022 SE37, which is approaching the Earth.
What is known about this asteroid and can it pose a danger to us?
Here are the pictures of the asteroid that have been taken by a 25-cm telescope in the village of Kochevanchik, Russia, and a 50-cm telescope of the Kuban State University.
Asteroid 2022 SE37 was first observed on September 28, 2022. It belongs to the Apollo group. Its exact size is unknown, but it is estimated to be between 308 meters and 689 meters in diameter.
2022 SE37 orbits the Sun in an elongated orbit with a period of 3.45 years (1,261 Earth days). During its rotation, the asteroid approaches the Sun by 120 million kilometers at most and moves away by 563 million kilometers at most.
The asteroid 2022 SE37 poses no potential risk to us: according to scientists, the asteroid 'does not pose a danger to the Earth in the foreseeable future.'
It is believed that scientists have already calculated the orbits of most asteroids, which can be somehow dangerous for the Earth, and 2022 SE37 is not among them, said Yuri Balega, an academician of the Russian Academy of Sciences.
"This is another one of almost 30 thousand asteroids already discovered by astronomers of the world. It flies away from our planet at a distance of many millions of kilometers and poses no danger to the Earth," the astronomer told Russian TASS News Agency.
Recently, scientists from NASA decided to test whether it's possible to change the course of the asteroid if a spacecraft crashes into it. As part of this project, the mission spacecraft DART on September 26 crashed into the asteroid Dimorphos at 24,000 kilometers. Dimorphos did not pose a danger to the Earth, but scientists wanted to see if the spacecraft could change the trajectory of the asteroid with kinetic force alone, knocking it off course just enough to keep the Earth out of danger.
The results of the mission are not yet known. NASA experts will monitor Dimorphos with ground-based telescopes to confirm that the impact of DART changed the asteroid's orbit around Didymos. Researchers expect the impact to shorten Dimorphos’ orbit by about 1 percent, or about 10 minutes. Accurate measurement of the asteroid's deflection rate is one of the main goals of the full-scale tests.
If the mission is successful, hitting the asteroid with a flying ship will be one way to protect the Earth from dangerous asteroids. If the mission fails, scientists will have to look for new, more effective ways to protect our planet.
