Asteroids hit the earth in 2029.

I'm not sure if it will hit the earth, but there is a 7% chance that it will enter our earth orbit. The name of the asteroid is: Destroyer.

Destroyer (99942 Apophis, asteroid 99942, translated into Apophis, temporarily numbered 2004 MN4) is a near-earth asteroid. So far, among all asteroids observed by scientists, it is the only celestial body that may hit the earth.

Initially (from its discovery on June 19, 2004 to February 27, 2004) * * Nearly 200 observations show that this asteroid reached the nearest position in the eastern hemisphere of the earth at 4:49+8 GMT on April 14, 2029, and collided with the earth at about 5:20+8 GMT.

If an impact occurs, it will release 6,400 trillion kilojoules of energy, equivalent to 1.53 trillion kilograms (1.53 billion tons) of TNT explosive. According to the observation reports of June 20 13 and 1 year, all the possibilities of destructive stars hitting the earth in 2036 have been ruled out.

Discovery process

Apophis was discovered on June 9, 2004/kloc-0 by Roy Tucker, David J. Tholen and Fabrizio Bernardi, who are engaged in asteroid research at kitt peak national observatory in Arizona, USA.

The observation team followed the destroyer for two nights. On June 5438+February 2, 20041day, the destroyer passed at a distance of 0.0964 AU (14.42 million km) from the Earth. From June, 5438 to October, 2005, its orbit model was further improved by using radar astronomical survey.

By February 24, 2004, 65438+, scientists of NASA have calculated that the possibility of hitting the earth in 2029 is as high as 1/450. After that, the observation and calculation continue, and the highest possibility of it hitting the ground in 2029 will reach 1/233.

The news was quickly announced to the whole world, but at that time, the eyes of the whole world were attracted by the Indian Ocean tsunami. At first, the news did not attract much media and public attention. This prediction is made in a probabilistic way based on observation.

The All-Russian Institute of Civil Defence and Emergency Situations of the Ministry of Emergency Situations of the Russian Federation predicts that it will be closest to the Earth in the spring of 2029.
