US media: A buses of asteroids passing over the earth today

According to the American Fun Science website, a small asteroid of a bus will fly next to the earth on the 7th. At that time, it will only be 56,000 miles (about 90,000 kilometers) from the earth, about 23% of the average distance between the earth and the moon. Essence And no one knew it was coming a few days ago.

It is reported that according to the calculation of the Jet Promotion Laboratory of Passadina, California, the US Astronautics Agency, the asteroid named 2022NF is expected to safely pass through the earth.

The report also said that astronomers used the data from the panoramic patriarchal telescope and the rapid response system to find this secret asteroid. The panoramic tutoring and fast -moving response system is a system composed of a camera and telescope located in Hawaii. The main goal is to detect near -ground celestial bodies. On July 4, the researchers determined the celestial body and calculated its approximate size and trajectory. It is estimated that the size of the space rock at the longest axis is from 18 to 41 feet (5.5 meters to 12.5 meters) at the longest axis (5.5 meters to 12.5 meters). Essence

Sister website of Fun Science Website Space Website said that due to small heads, 2022NF does not meet the standards of the US Aerospace Administration for "potential dangerous asteroids" -generally up to at least 460 feet (140 meters), not from the earth, not the earth By 4.6 million miles (7.5 million kilometers). Although the new asteroid will be far less than that distance when the new asteroid flying next to the earth, it is too small to not pose a threat to the earth.

The report pointed out that although the asteroid was closest to the earth on the 7th, from the 6th, some telescope could be seen.
