“Hellouinsky” asteroid was a complete surprise to scientists – Russian newspaper

On the approach to the planet of a celestial body has informed agency NASA. He was named 2015 TB145. According to scientists, 31 October, on Halloween, the asteroid will pass at a distance of 499,000 kilometers from the planet, which is equal to 1.3 of the distance from Earth to the Moon. Its diameter ranges from 280 to 620 meters. Speed ​​- 35 km / s. NASA calmed earthlings, assuring that the planet intruder does not represent any danger. Last time such a celestial body flying in the vicinity of the Earth in 2006. Next rapprochement with the planet asteroid of this size will take place in August 2027.

Note

Dmitry Vibe, Head of Department of Physics of stellar evolution of the Institute, Doctor of Physical and Mathematical Sciences Astronomy:

What distinguishes this asteroid from a variety of other celestial bodies, which flies to the Earth? Firstly, it will pass fairly close to the planet, and secondly, its considerable size, in the third, but the main thing – it was a complete surprise to scientists. Earlier, no one was watching. The fact that the search for celestial bodies such size is extremely complicated. Until recently, scientists were engaged in the discovery of the bodies of more than 1 kilometer in diameter. Now this problem is practically solved, and there is a new task – to find 90 percent of the bodies of more than 140 meters. While about 80 percent of known asteroids with a diameter of 500 meters, about 50 percent of the size of 300-500 meters and only 10 percent of the bodies in the 140-300 meters.

Why such a large spread diameter is now approaching asteroid to us? The fact that it is very difficult to measure. To do this, hold a radar. This asteroid is detected optical telescope that is Hawaii and automatically scans the sky. It gives information about the brightness of the asteroid.

As for the assertion that following such an asteroid will fly in 2027, then we can talk only about the known celestial bodies, and the intruder may appear at any time.
