MOSCOW, November 27 — RIA Novosti. NASA working on the 70-meter radio antenna at Goldstone (California, USA), conducted a series of radar observations of asteroid 2007 PA8 during his last in this century, a close encounter with Earth — the data can accurately measure its orbit, to investigate details of the surface and calculate the period rotation, according to a statement on the website Space Agency.

Asteroid 2007 PA8 opened August 9, 2007 the participants of the project on the study of near-Earth asteroids LINEAR (Lincoln Near Earth Asteroid Research). This 1.6-kilometer asteroid entered the class of potentially dangerous, but for the foreseeable future, it is no threat to Earth.

On Monday, November 5, at 16.42 GMT (20.42 MSK), is a celestial body flew at a minimum distance from the Earth — at 0.043 astronomical units (the average distance from the Earth to the Sun). However, this value is 6.48 million kilometers and 16.82 times the distance from Earth to the Moon. The next convergence at roughly the same distance will happen in December 2122, when the 2007 PA8 fly in 0.044 AU from Earth.

Radar measurements using the Goldstone radar allowed scientists to accurately calculate the trajectory of an asteroid for the next 632 years. In addition, the radar images were discovered craters, boulders — the best resolution images is about 3.75 meters per pixel.

In addition, researchers found that the asteroid has a very slow rotation — it makes one revolution in about 3-4 days.
