According to preliminary estimates measurements QE2 asteroid aerospace metals measured approximatel

A first sequence of radar images of asteroid 1998 QE2 is taken in the evening of 29 May 2013 thanks to scientists with NASA's 70-meter radio telescopes at Goldstone, Californi, when the asteroid was about 6 million miles from Earth, approximately 15.6 lunar distances. Images show the asteroid 1998 QE2 is a binary system aerospace metals consisting of a main body and a smaller that revolves around it.
Radar images have suddenly aerospace metals discovered that asteroid 1998 QE2 is a binary asteroid. In practice, some larger body size about 2.7 km, is another small object, which however could do much damage, if hypothetically he falls to Earth.
According to preliminary estimates measurements QE2 asteroid aerospace metals measured approximately 600 meters in diameter. The two friends are now on the road asteroids away from Earth, reaching the closest point on Friday 31 May.
Among all the asteroids that pass near Earth are more than 200 meters aerospace metals in diameter, about 16 percent aerospace metals is made up of two or more objects. Radar images show the main body, or primary, is about 2.7 km in diameter and has a rotation period of less than four hours.
Researchers also pointed out some of the features of the surface of the main body: radar images for QE2 in fact suggest the presence of a large seal on the surface.
The closest approach of the asteroid occurred on May 31 at 22 hours, when the asteroid was not less than 5.8 million kilometers from Earth, about 15 times the distance between Earth and the Moon.
This is the closest approach to asteroid will make at least for the next two centuries. The asteroid 1998 QE2 was unveiled on 19 August 1998 by the LINEAR program at the Massachusetts Institute of Technology.
The resolution of these images is still quite low, but other data must reach the view that 1998QE2 between 30 May and 9 June, astronomers aerospace metals have emphasized aerospace metals two in the top of radioastronomisë jewelry, one from 70 meters in the Goldstone aerospace metals radar NASA , in California, and one at the Arecibo Observatory in Puerto Rico. The two telescopes are complementary imaging capabilities that allow astronomers to learn as much as possible about the asteroid during his brief visit near Earth.
Radar measurements are an important technique to study an asteroid the size, shape, rotation state, surface characteristics and to improve the robustness and calculating the orbits of asteroids. Radar measurements often allow the calculation of the orbit of asteroids for many decades to come. This allows to predict the risk that some of these objects may represent the Earth.
Americans aerospace metals seem to have more interest in objects that reside in the space around aerospace metals the Earth, in order to increase the budget of NASA program (NEO stands near-Earth) from six million to 20 million dollars. NASA also wants to try to capture an asteroid and put it into orbit around the moon and then send a manned mission to study it closely.
Also some private companies seem to exploit asteroids interested in economic terms. No fear at all of the technical difficulty of the enterprise, they would like to use water and metals present in the rocks â <â <directly in space, to avoid bringing building materials for future space missions from Earth.
But to start this seems to NASA, which in 2016 will launch a robotic probe in one of the familiar objects m & e
