Astronomers did not notice the asteroid 2021 SG, which was closest to Earth on September 17, and did not detect it until it fell directly near Earth, i.e. 240,000 km away.
This is less than the distance that separates the Moon from the Earth.
This was acknowledged by Paul Chots, NASA’s Director of Space Exploration. Why did it happen? – Because, 2021 S.G.

Scientists believe that its length is not more than 94 meters and its width is not less than 42 meters. But his speed reached 68 thousand kilometers per hour. If this asteroid fell on Canadian soil, it would have caused severe damage. Just as an asteroid crashed in the cities of Sodom and Gomorrah 3,600 years ago and killed 8,000 people, it would have caused a local tragedy if it had fallen on a Canadian city.
The asteroid orbits the Earth once every 27 months.
Last year meteorologists did not notice the 10-diameter meteorite 2020 VT4, which approached Earth at a distance of 380 km and flew over the British Pitcairn Islands in the South Pacific. It had to collide with the International Space Station, flying at an altitude of 340 to 430 km. Fortunately, the station was located in an area of the South Atlantic.
Also in 2018, astronomers observed the 20-meter-diameter asteroid 2009 FH, the day before the dangerous approach to Earth. The asteroid flew at an altitude of satellites (32,000 km).
And all these meteorites, the asteroid “Chelyabinsk” that fell in the Ural region of Russia, came from the direction of the sun, so it is difficult for astronomers to find them.
Humanity is still threatened until 2026, when the NASA NEO Surveyor space telescope operates infrared, which can detect dangerous asteroids coming in day and night, millions of kilometers away from the sun.

Shafagna – The James Webb Space Telescope (JWST) has detected water in the inner region of planet-forming gas and dust surrounding a newborn star.
The discovery is important because water, along with other molecules needed to form Earth-like worlds, is near many young, massive stars that produce intense ultraviolet radiation.
Such extreme environments were previously thought to be unsuitable for rocky planets to form, but the new discovery suggests that Earth-like planets can form in a wider range of cosmic environments than previously thought.
The results could help scientists better understand how the Solar System’s planets formed about 4.5 billion years ago.
The research also represents the first results from JWST’s Extreme Ultraviolet Environments (XUE) project, which aims to characterize the environments and chemistry of massive rotating disks of dust, gas and rock around young stars. and comets.
Team leader María Claudia Ramírez-Danos, a scientist at the Max Planck Institute for Astronomy in Germany, said: “The James Webb Space Telescope is the only space telescope with the spatial resolution and sensitivity to study planet-forming disks in regions of massive stars. Formation.”
The first results of XUE come from observations of a protoplanetary disk called XUE 1, located in the star cluster Bismis 24.
XUE 1 is one of 15 protoplanetary disks in NGC 6357 that are being studied as part of the XUE project.
The team expected the observations to show that XUE 1 had been exposed to high levels of ultraviolet radiation, but they were surprised to find that the protoplanetary disk was filled with tiny, partially crystallized silicate dust.
The researchers found traces of molecules such as carbon monoxide, carbon dioxide, hydrogen cyanide and acetylene.
“XUE1 shows that the necessary conditions exist for rocky planets to form, so the next step is to check how common this is,” Ramírez-Danos said. “We will monitor other discs in the same area to determine the frequency with which these conditions are seen.”
Details of the discovery have been published in The Astrophysical Journal Letters.
