05.04.09. Astronomers have found quite a large asteroid on an unusual orbit that can zoom in to the Earth at a distance of 3.5 million kilometers.

Asteroid 2009 HC82, judging by his brilliance, has a size of 2-3 km and orbits in the direction opposite to the treatment of most bodies in the solar system at an angle of about 25 degrees to the plane of Earth's orbit.

As British popular science magazine New Scientist, the object was opened on April 29 as part of a sky survey Catalina. Elongated orbit of the object, calculated from the first observation, from time to time brings it closer to Earth at a distance of about 3.5 million kilometers, and for this reason, it belongs to the potentially hazardous asteroids.

2009 HC82 returns to its point nearest to the Earth's orbit every 3 years and 5 months, but not every time it is at the Earth's orbit that is closest to the orbit of the asteroid is Earth. Relatively near closest approach will take place January 4, 2012, when the asteroid is about 23 million miles from Earth.

The unusual orbit of the asteroid may mean that it is a rocky core "faded comet", captured the major attraction of the planets from the Oort cloud, but have spent a volatile external covers for many millions of years around the Sun.
