An asteroid can destroy life on earth in the year 2880 Bashny.Net

Scientists have named a new potential date for the destruction of all life on Earth. The asteroid called 1950 DA will collide with our planet on March 16, 2880.





Given the current speed of the asteroid killer and the fact of its rotation around its own axis, it should fall apart into small fragments before collision with the Earth. But scientists from the University of Tennessee in Knoxville is not much hope on this scenario. They assume that all parts of the asteroid holding back with each other traction.

Previously, scientists believed that asteroids are not falling apart due to gravity and friction. But a new study shows that these laws do not apply on 1950 DA. With a diameter of 1 km, it makes one revolution around its own axis in 2 hours and 6 minutes. At that speed he should have been long apart, but this did not happen, and no sign of the forthcoming destruction either. The researchers calculated the temperature and density of the new asteroid and found that it does not fall apart interatomic interaction.

1950 DA is rotating so fast that at the equator, he noted the negative effect of gravity, if an astronaut tried to walk on the surface of the asteroid, the result would have cast into space.

The results of the new research presented in the journal Nature. This article describes possible scenarios for preventing collisions with an asteroid. Question prevent the collision of our planet with asteroids being raised more often: the need to reinforce the recent fall of the meteorite in Chelyabinsk.

The discovery of the asteroid 1950 DA has forced researchers to give up some methods of dealing with them. For example, if you push this object with another asteroid, the resulting small stones still reached the Earth's surface.
