Blogger Trends - Giant Asteroid Approaching Tuesday - An asteroid larger than an aircraft carrier - or four times the big football field - will pass between Earth and Moon, Tuesday, November 8, 2011. He is in a distance of closest approach to Earth in a period of 35 years.
Asteroid 2005 YU55, will float within a range of 201,700 or about 325,000 miles - into the orbit of the Moon. Previously, he was known to within "a stone's throw" with the Earth 200 years ago.
How bahayakah for humans?
Professor of Earth and Atmospheric Sciences Purdue University, Jay Melosh, an estimate if it hit Earth, it creates 2005 YU55 crater roughly four miles or 6.4 kilometers and within 1700 feet or 520 meters. He also could trigger a magnitude 7 earthquake and tsunami waves as high as 70 feet.
However, Melosh said the asteroid, discovered in 2005 was not harmful to the Earth.
The U.S. space agency, NASA also has ensured that the asteroid 2005 YU55 no harm. "We are very sure, 100 percent sure, this asteroid is not a threat," said Director of the Near Earth Object Program at NASA's Jet Propulsion Laboratory, Don Yeomans, of NASA as the site loaded.
If Earth is in danger, what about the Moon? Therefore, the trajectory of 2005 YU55 actually closer to the Earth's satellite.
Yeomans said the asteroid was also not going to hit the Moon. When passing a giant space rock with a speed 13 kilometers per second, one-quarter Moon will be on his travels in the opposite side of Earth.
If hitting the Moon, says Yeomans told Life's Little Mysteries, it will not cause great damage, even though "will create a crater of the collision, at least as wide as 4 kilometers". That's significant, but still small compared with the countless other moon crater.
Astronomers classify as asterodi 2005 YU55 as type C, containing carbon. "Not just a stone like the others," said Yeomans.
Such asteroids are believed to have collided with Earth in the past, bringing carbon-based materials and also water to Earth early in its formation. The threat of such a collision with an asteroid is thought likely to occur within 100 thousand years or more.
In addition to 2005 YU55, a giant asteroid will pass close to Earth as well. His name: Apophis. Which some people called a "carrier doomsday". With a length of 269 meters, he will be in very close proximity to Earth on April 13, 2029, but not to hit. However, when returning passed on 13 April 2036, he had a slim chance to nudge the Earth.
