Washington, June 23: A potentially hazardous asteroid, on Thursday 14 lunar distances from Earth, slipped inside to secure it to enter, 500 meters wide, like a mask of civilization - is the murder of the LZ1 asteroid.2012 may not be a risk, but more of a concern rooted in the alert at the end of their identity - the asteroid was discovered only four days before closest approach.
It is in the skies of the southern hemisphere, because there is no reason for its late discovery, we have some of the world as part of the asteroid - see programs. If a collision course with Earth, ie, a few days notice of the existence in the time.So, fly in the sequel of the famous Arecibo Observatory in Puerto Rico, astronomers at the radar image to be used to interloper . What he discovered was an interplanetary shock - asteroid 2012 LZ1 is larger than originally thought, in fact, too big. LZ1 2012 km wide, is twice the original estimate.
Optical observations of the team contributed to the low initial estimate of Arecibo, it reaches the light is reflected only 2-4 percent in 2012 LZ1 decided that the surface is really dark.To produce radio waves beamed in the direction of the asteroid with the Arecibo, Arecibo planetary radar that is used as a powerful radar.Incredible high resolution images on the surface of the bounce back radio antenna by measuring the signals are given here. Made very precise measurements of the physical magnitude of the asteroid.
"We're still learning about the population of asteroids be the object, it will be important that the radar observations, a little higher than expected and became," he told Discovery News in low Arecibo Observatory of the statement quoted Ellen Howell.Follow-up observations of the astronomers of asteroids accurate estimate of the orbital characteristics of form and helped support other.With Arecibo astronomers are unsure of the Earth to be hit by at least 750 years occur in 2012 LZ1.
"Our radar is a measure of the sensitivity of the properties of the asteroid, and not affect at least the next 750 years, to identify the land that gave us permission," said Mike Nolan, Arecibo Observatory radar Director Planetary Sciences, said.
