Asteroid “just misses” Earth / News / The Foreigner

Asteroid “just misses” Earth. At 14:30 this afternoon, an asteroid flew past the Earth at a distance of 75,000 kilometres. This is nearer than the moon.  According to TV2.no, the asteroid was 30-40 metres in diameter, and had the same amount of energy as a five to thirty megaton nuclear bomb. One of similar size exploded in Tunguska in Siberia in 1908. “Although the cause is the subject of some debate, the explosion was most likely to have been caused by the air burst of a large meteoroid or comet fragment at an altitude of 5–10 kilometres (3–6 miles) above Earth’s surface. Different studies have yielded varying estimates for the object's size, with general agreement that it was a few tens of metres across,” according to Wikepedia.DD45
