Earth-threatening asteroids

very large asteroids threatening Earth

astronomers around the world have discovered an asteroid that will pass near the Earth around the 18th April 2011. the astronomers explained that these asteroids are very large at all equivalent to 20 times the atomic bomb. at this distance of the asteroid is about 11 times the distance of Earth to the moon.

This asteroid sightings glowing fairy lights, this makes very interesting to astronomers, the asteroid was moving very fast spinning from one end to a long and shaped like a cigar.

"which means that the asteroid is elongated and can be seen from the length and the narrowness of the asteroid when it is being rotated" said Don Yeomans, Manager of Near-Earth Object Program Office, NASA.

estimated asteroid measuring 50 meters long, and has a rotation period of about 7.5 minutes.

however, Don Yeoman stated that this asteroid will not threaten the earth and not have to worry about asteroids, both in the near future or in the future.

Yeomans said, is certainly good news. Because, although the size of 50 feet sounds small, but the size was 5 times larger than the asteroid that exploded 15 kilometers above Indonesia, in October 2009.

For information, when the asteroid that exploded, he issued the same energy with the power of three atomic bomb explosion. That is, this time the asteroid was found to have 15 times the explosive power of atomic bombs if it arrives at the Earth's atmosphere.
