Near earth flew rare double asteroid


                                Возле земли пролетел редкий двойной астероид

The object represents the two cosmic bodies with a size of about 900 meters, rotating around each other.

Near-earth asteroid 2017 YE5 was first discovered by the Observatory of Morocco in Oukaimedene December 21, 2017, but no details about the physical properties of the asteroid was not known.

On 21 June, the asteroid 2017 YE5 as close to the Ground, at least in the next 170 years. Then the data obtained using the NASA Goldstone Solar System Radar (GSSR) in California, showed the first signs that 2017 YE5 can be a double asteroid.

By the end of June astronomers of the Arecibo Observatory in Puerto Rico and Goldstone in California were able to accurately determine that the asteroid 2017 YE5 consists of two parts. New observations show that the two objects rotate around each other every 20-24 hours.

Scientists have estimated that among the near-earth asteroids larger than 200 meters, about 15% are binary with one large object and a much smaller companion. Binary asteroids are of equal mass, such as 2017 YE5, are much rarer. This is only the fourth such asteroid, which could find astronomers.
