Dante Lauretta, a professor of planetary science at Arizona University in the United States, pointed out that the orbit of the asteroid Bennu will gradually move closer to the earth due to the gravitational influence of the earth, and when it collides with the earth at the end of the 22nd century, it is likely to cause mass casualties on the earth.

According to the British Daily Mail, planetary science expert Lauretta pointed out that the near-Earth asteroid named Bennu passes by the Earth in orbit between the Earth and the Moon every 6 years. Lauretta predicted that when Bennu flew over the Earth in 2135, the orbit would change due to the gravitational influence of the Earth, so that it would collide with the Earth at the end of the 22nd century.

Lauretta's calculations show that between 2175 and 2196 AD, Bennu had a 1 in 2700 chance of colliding with Earth, and the Earth was likely to suffer serious casualties. Bennu orbits the sun at a speed of more than 100,000 kilometers per hour, and if it collides with the earth, it is equivalent to detonating 300 million tons of explosives, and the power can be imagined.

In order to monitor the condition of Bennu, NASA will launch the probe OSRIS-REX in September to collect Bennu samples for analysis, and the probe is expected to stay on the surface of the planet for 1 year and return to Earth in 2023.
