The Solar system, as well as at comets, has a tail. To such conclusion came the American
scientists supporting mission of the automatic device of NASA IBEX. It was brought by National administration of the USA on aeronautics and research of a space (NASA) to Earth orbit in 2008. According to NASA, to such results it was succeeded to come as a result of the complex analysis transferred by NASA IBEX for the first three years of work. The tail of Solar System consists of two streams of quickly moving loaded particles proceeding from our star from above and from below. Also in the tail of Solar System there are two more streams of slowly moving loaded particles on each side. Under NASA certificate, the American experts don’t know precisely, what extent of this loop. With help of the NASA IBEX tools hopes to receive idea of all structure of a heliosphere, and also to establish, where exactly there passes border of a shock wave on which there is a delay of a solar wind. Earlier interplanetary probe of NASA Voyager-1, started 35 years ago, crossed heliosphere border. The device became the artificial object first in the history which has left Solar system. Border of Solar system is considered the so-called heliosphere – bubble, filled with a solar wind. Beyond its limits begins the interstellar space which property doesn’t depend any more neither on a magnetic field, nor on a stream of the loaded particles proceeding from the Sun.
