In new observations, scientists used the maximum approach of asteroids from the Earth when they flew about six million kilometers from us

In June, astronomers studied the near-Earth asteroid 2017 YE5, which is under
Naked Science with reference to NASA reported
Small asteroids were found with three radio telescopes, they emit radio waves to the nearest asteroids and wait for a signal to appear. use the signals received to understand the shape of the asteroid

In the case of 2017, YE5 scientists found that it seemed to be one of my asteroid – particles. in fact, two separate bodies performing a turn around one every 20-24 hours
This result is really interesting, since both sides of the asteroid is almost the same size – about 900 meters from diameter. Until now, scientists have managed to detect only three other "ideal" pairs. Most double asteroids vary in size, where one darkens the other half.
New observations in 2017 YE5 revealed another surprising feature of the asteroid: the stones are not identical. One of its halves seems much darker than the other. This may indicate that they differ in composition or texture.

However, it can take a long time before scientists can reveal the secrets of this pair. New observations have been made on the maximum approach of the asteroid to Earth, when it flew at a distance of about six million kilometers from us. The next convergence of this type will take place over 170 years.
