A number of amateur astronomers from around the world have discovered an asteroid that is expected to pass near the Earth on Monday night, April 18, 2011.
Currently, the asteroid 2011 GP59 was located at a distance 10 times than the distance of Earth den gan months.The appearance of asteroids that flickering makes the interested observer. Apparently, it is known that the cigar-shaped asteroid is rotating from end to end quickly.

"Generally, if there are asteroids such force, means the object is elongated , and we see the long side and then the side of narrowness when he spins, "said Don Yeomans, Manager of Near-Earth Object Program Office, NASA, as quoted by News.com,
GP59, says Yeomans, an estimated length of 50 meters and the rotation period to reach about 7.5 minutes. "This makes the brightness of the object was changed every 4 minutes," he said.
However, the Yeoman of the agency in charge of tracking the characteristics of asteroids, and comets protect mankind from the blow of these things mentioned, we need not worry.
"Although New found, the location of the asteroid's orbital 2011 GP59 can be determined, "he said. "There's no chance this space rock enters Earth's atmosphere when it passed in the near future, or in the future," he said.
This, said Yeoiman, is certainly good news. Because, although the size of 50 feet sounds small, but the size was 5 times larger than the den gan asteroid that exploded 15 kilometers above Indonesia, in October 2009.
For information, when the asteroid that exploded, he issued the same energy den gan explosive power of three atomic bombs. That is, the asteroid that was found this time had 15 times the explosive power of atomic bombs if it arrives at the Earth's atmosphere.
Fortunately, if the asteroid that exploded over Indonesia escape the observation of astronomers, at least the asteroid that will approach this time is unknown.
