Voyager 2 has reached border of Solar system


The Voyager 2 station, perhaps, has approached borders of Solar system, NASA.K reports to such conclusions scientists have come, having analysed given from the scientific CRS tool (Cosmic Ray Subsystem) of the spacecraft. The device during the period since the beginning until the end of August has registered increase in energy of the space beams reaching Voyager 2, approximately for five percent. The similar phenomenon was observed in May, 2012, in three months before when the Voyager 1 station has crossed a heliopause, having appeared in interstellar space. Now Voyager 2 is at distance about 17,7 billion kilometers from Earth (in 118 times more of distance between our planet and the Sun). The Voyager 2 team recognizes that the environment around the station changes, however notes that increase in energy of space beams can't be considered final sign of passing of a heliopause which provision changes during a 11-year cycle of solar activity. Borders of Solar system are defined by two ways. It agrees to the first, limits decide by a heliosphere (a magnetic analog of the atmosphere of planets), to the second — the sphere Hilla (area on the defining gravitational influence of the central celestial body). For the Sun the radius of the sphere Hilla is estimated at one-two light years. Voyager 1 and Voyager 2 spacecrafts are identical, the starting mass of one station (together with a hydrazine) — 815 kilograms. In expanded form the device is located in a cube with the party four meters. Voyager 2 started in August, 1977 for 16 days before Voyager 1. Devices, besides the scientific equipment, bear messages from mankind to possible alien civilizations.

Still any spacecraft didn't fly by so close to the last two planets.Voyager 1 has gone on other trajectory — after flight of Saturn the spacecraft has gone not to Uranium and the Neptune, and at once to interstellar space. In December, 2011 Voyager 1 has left heliosphere limits, having become the first man-made object which has appeared around a heliopause (separates a heliosphere from interstellar space). It is considered that three radio isotope thermoelectric generators will allow Voyager 1 and 2 to keep in contact with Earth approximately till 2027. As show estimates, Voyager 2 through 40 thousand years will fly by at distance 1,7 light years the dim red dwarf of Ross 248 which is at a distance of 10,3 light years from Earth in Andromeda's constellation.
