The space rock will “touch” the Earth on June 24 to 8:44 (Italian time): at that moment, it will be a 3.7 million kilometers from the earth. Despite looking a lot, this is classified by NASA as “close approach “. Fortunately, the chances of the space rock hitting us are extremely low. “Nobody should be overly concerned about the impact of an asteroid or comet on Earth. The threat to anyone of road accidents, diseases, other natural disasters and a host of other problems is much higher than the threat of NEOs (near-Earth objects)”, Explains NASA.
However, the American space agency did not rule out the possibility that an asteroid could collide with our planet in the near future. “Over long periods of time, however, the chances of Earth being hit are not negligible. At the moment, our best insurance is up to NEO scientists and their efforts to find these objects first and then track their movements in the future. We have to find them first, then keep an eye on them”Added NASA.
If an asteroid were to be found on a collision course with Earth, NASA has several tactics up its sleeve to avoid a collision.”One of the suggested techniques for deflecting an asteroid includes nuclear fusion weapons that explode on the surface to slightly change the speed of the asteroid without crushing it. The high-speed neutrons from the explosion would emit a shell of material on the surface of the asteroid. The material in this shell would expand and explode, producing a kickback on the asteroid itself. A very modest change in speed in the movement of the asteroid (only a few millimeters per second), acting over several years, can cause the asteroid to completely miss the Earth. However, the trick is gently push the asteroid to safety and don’t blow it up. The latter option, although popular in movies, only creates a bigger problem when all the fragments meet Earth. Another option that has been discussed includes creating large solar sails on a small dangerous object, so that the pressure of sunlight can eventually redirect the object away from the expected collision with Earth “, explains NASA.
