A dangerous object equivalent to 22 atomic bombs approaches the Earth every six years

In the 1998 American science fiction disaster film “Armageddon”, a meteorite the size of Texas is about to hit the earth. If it happens, it will cause a devastating blow to the earth. In the play, the National Aeronautics and Space Administration organized a professional team and sent two spacecraft to prevent the meteorite from attacking. In the end, after many sacrifices, they successfully split the huge meteorite into two and prevented an unprecedented destruction. Humanity’s ability to respond effectively is due to the early discovery of the existence of dangerous celestial bodies. This is indeed the case in reality, and observations and investigations of potentially dangerous celestial bodies are carried out.

Celestial objects with a diameter of 500 meters have the destructive power to affect the earth. On average, one will appear every 130,000 years. In 2010, scientists said that eight asteroids had the possibility of impacting the Earth between 2169 and 2199. One of the asteroids was named “Bennu”. The “Sentinel System” of the Center for Near-Earth Object Research ” pointed out that its Palermo impact risk index reached level three, and it is among the small celestial bodies with the highest risk of impacting the earth. Bennu is “Asteroid 101955”. It was first discovered by the Lincoln Near-Earth Asteroid Research Group in 1999. It was named after the phoenix bird in Egyptian mythology – Bennu, named after a 9-year-old child named Michael Pugh. Named by Zio. Subsequent naming of the landforms on this asteroid are all related to mythical birds, such as “Roc Rock” taken from Arabic mythology; “Simorg Rock” from Persian mythology; “Fujin” from Nordic mythology Rock”.

For this asteroid, the probe of the Osiris mission went to it to collect samples on October 20, 2020, and set off to return to Earth on May 10, 2021. It will return this year for analysis. Scientists have spent more than two years studying relevant information about Bennu, hoping to uncover the time and path when it may hit the Earth in the future. As the most likely threat to impact the Earth, Bennu has a diameter of 492 meters and passes near the Earth approximately every six years. The best collision estimate from 2014 indicates that it has an accumulation of 0.037% between 2175 and 2196. The probability is that it will occur on September 24, 2182. By 2135, Bennu is expected to pass through the area between the Earth and the Moon, and before 2300, the probability of impact is about 0.06%.

If Bennu eventually hits the Earth directly, its destructive power is equivalent to the explosion of 22 atomic bombs, with the destructive power to wipe out a surrounding area of ​​about 965 kilometers. Research has found that the probability of impacting the Earth is slightly higher than previously predicted. According to reports related to NASA’s “Asteroid Hunting Satellite”, this near-Earth object space telescope has the ability to observe near-Earth objects day and night and is expected to be launched in 2026. Even though there are some potentially risky asteroids, with continued observation and research, there is currently no need to worry too much about the threat from these extraterrestrial visitors. Perhaps more secrets of the universe can be discovered in the samples retrieved by the detectors. .
