The asteroid which just missed Earth last year, flew not one

Teams of three of the world’s largest radio telescopes involved in the observations of the asteroid 2017 YE5, which is June 21, 2017 flown 6 million miles from Earth is 16 the distance to the moon. Astronomers radar NASA in California (using NASA’s Goldstone Solar System Radar — GSSR), Observatory in Puerto Rico (Arecibo Observatory in Puerto Rico) and Observatory in West Virginia (Green Bank Observatory – GBO) managed to get the image of the heavenly guest, of which it became clear that the asteroid — double.

Asteroid 2017 YE5 revolves in the vicinity of our planet in an elliptical path.

Lump of the asteroid 2017 YE5 rotate relative to each other.

It was believed that the us was flying one block size of nearly a mile. And there were two of them. Almost kilometres — or rather, at 900 metres in width. As reported by NASA, the blocks rotate relative to each other, making one revolution in about 24 hours. Light reflect poorly if they are black as coal. What exactly is, is still unknown. The analysis of the collected data continues.

According to astronomers, the double asteroid binary, scientifically, is not uncommon. Of about 15 percent among dangerous space rocks — those with a diameter of more than 200 meters. But 2017 YE5 different from them. Usually in a “set” of binary asteroid is part of one large object and other smaller ones. Asteroid surveyed now consists of two blocks of the same size.

To protect themselves from double strike, if there is such a threat, will be much more difficult. If at all possible.

Asteroid 2017 YE5 unlikely to be in the vicinity of our planet in the next 170 years. However, it is considered near-earth, and therefore at risk. Not only theoretical.

By the way, recently scientists have demonstrated that missile with nuclear warhead can be an effective weapon against asteroids several hundred meters in diameter. The details of their experiments here:

Observations showed that was bearing down on us two huge chunks at once.
