Asteroid Earth Nov. 8
November 3, 2011 by staff
Asteroid Earth Nov. 8, An asteroid of 400 meters in diameter safely beyond the run of the Earth a little closer to the lunar orbit on November 8. The space rock known as 2005 YU55 will be close to 324,600 km of Earth’s surface, making it the closest encounter this space rock has been done in 200 years.
Scientists are trying to fly over 2005 YU55 as an objective science of opportunity – allowing it to beanlyzed during the stile and offer clues about the formation of the Earth.
The asteroid-sized aircraft carriers will be followed by a 70-meter radar telescope in the Deep Space Network space agency NASA’s Goldstone, California, from November 4 through November 10, and the Global planetary radar at Arecibo in Puerto Rico will begin tracking the asteroid on November 8.
2005 YU55 images obtained from Goldstone is expected to reveal a wealth of detail about the characteristics of the asteroid’s surface, shape, dimensions and other physical properties.
2005 YU55 poses no threat of collision with Earth for at least the next 100 years, according to Don Yeomans, manager of the Near Earth from NASA Object Program Office at the Jet Propulsion Laboratory in Pasadena , California.
The last time a similar-sized space rock was as close to Earth was in 1976, but went unnoticed because astronomers did not know about the flyover at a time. The following approximation of a known asteroid of this size will be in 2028.
