Ground-based telescopes have detected an asteroid that flew about 350 kilometers from the surface of the Earth.
The incident occurred on November 13, but it became known only the next day – the first images of the asteroid were taken 15 hours after approaching the Earth. As N+1 notes, post-factum fixation is not uncommon for fast objects flying to the Earth from the Sun.
Astronomers estimate that the diameter of the asteroid 2020VT4 is from 5 to 10 meters. During its arrival to the ground it looked like a moving point with a star value of +3.
The orbit altitude of the ISS is 385 kilometers.
The Chelyabinsk meteorite, which fell in 2013, was the largest asteroid fragment with a diameter of about 17 meters, which was destroyed in the Earth’s atmosphere. The Chelyabinsk meteorite was the largest celestial body that reached the Earth’s surface after the fall of the Tunguska meteorite.
The previous record for the rapprochement of the asteroid with the Earth was recorded in August 2020. Then, the asteroid 2020 QG flew to the planet at a distance of about a thousand kilometers.
