The force that could deflect the asteroid Bennue from impacting Earth.

There is a probability in 2700 that Bennue will hit the earth on September 24, 2182 and a probability of total impact between 1750 that it will do so before the year 2300, it is very difficult to calculate exactly where the asteroid will be during its critical approach on 2135 And if it could go through the gravitational keyhole that would doom us.

The team looked at various types of small forces that can affect the asteroid as it orbits the sun, because even the smallest force given enough time can significantly deviate an asteroid's orbital path among those forces is the sun's heat, when an asteroid travels around. from the sun the sunlight heats up on its daytime side, because the asteroid rotates the heated surface will rotate and cool when I entered the night side, as the surface cools it releases infrared energy that generates a small amount of thrust on the asteroid a phenomenon called Yarkovsky.

In short periods of time this push is miniscule, but in the long term it can play an important role in changing the trajectory of an asteroid, although the chances of it hitting the earth are very low Bennue is still one of the two most known asteroids. dangerous parts of our solar system along with another asteroid called 1950 DA that is just over a kilometer in diameter.

Bennue is smaller, it is about 500 meters in diameter, its impact would not mean the end of the world or of humanity, although its damage would be catastrophic and could automatically disintegrate a large city, devastate a small country and temporarily alter the planet's climate, perhaps during several years.

Experts have calculated that the impact would generate about 1,200 megatons of energy, about 80,000 times the power of the Hiroshima atomic bomb, although without the emission of radioactivity, but its destructive power is still very far from the asteroid of more than 11 kilometers that it put end to the kingdom of the dinosaurs and it is calculated that it generated an energy equivalent to 100 million Megatone.
