Asteroid 1950DA was once thought to be quite a dangerous asteroid. In the year 2003, it was suggested by a study that if the Atlantic Ocean is impacted by the asteroid, the resulting tsunami waves will be around 200 feet high.
An unexpected turn was taken by the understanding of scientists of 1950 DA, this month. It was found that the asteroid is like a rubble pile and half of it is an empty space. As per a report from the University of Tennessee, it was found that the 1950 DA, rotates faster than the breakup limit for its density.
So, if this rubble pile is held together by gravity, it is assumed generally that this would fly apart. Therefore, they must be held together by interparticle cohesive forces.
These forces are also termed as van der Waals Forces. These are weak electric forces through which particles can be attracted together. With this, the asteroid can stay together in spite of the incredibly fast spinning motion. This is definitely a great news for humans, around 800 years from now. It is forecasted that the Earth would be hit by Asteroid 1950 DA in the year 2880. With todays news, the chances of it are less. The asteroid can be shattered even with a very small impact.
As per Rozitis, a researcher, with one of the asteroids being held together, complete disruption can be caused even with a small impulse. As per Rozitis “Following the February 2013 asteroid impact in Chelyabinsk, Russia, there is renewed interest in figuring out how to deal with the potential hazard of an asteroid impact”.
The potential mining missions to asteroids are also complicated with this news. Extensive research has to be done by governments and private companies on any potential mining candidates in future.
