An asteroid the size of three Big Ben, who recently missed earth, remains a threat to mankind. The fiery meatball whose name is “BN509” passed by Earth at a speed of 70,000 kilometers per hour. As argued astronomers, the asteroid – 400 long and 200 meters wide – past “worrying close” to our planet.
Although the fiery meatball missed our planet, NASA officials claim he is still potentially dangerous. According to them, one day the asteroid could hit the Earth.
The scientist Ed Rivera-Valentin says the object has the shape of comb and consists of two parts.
NASA regularly monitors objects that pass close to the ground. When the object will appear within 10 minutes appliances assess potential movement and alert scientists.
