Six months ago NASA spacecraft “Voyager-2” has left the solar space (the heliosphere) and went into space.
He became the second after “Voyager-1” synthetic probe, which overcame the boundaries of the Solar system.
In addition, in interstellar space can take probes “pioneer 10” and “pioneer-11” (now communication with them is lost, and to establish the whereabouts of the impossible) and “New horizons” (New Horizons).
“What is our life? Game!”“World mind games”: the premiere of “the World” Sooner or later, all objects run out of fuel, but they will continue to drift in space for thousands or perhaps millions of years, reports .
In a recent study, scientists figured out a possible route for each of them. They used the same technique as in the case of asteroid Omului (the first interstellar object, seen in the Solar system).
It is known that the nearest to the Sun, the star Proxima Centauri. “Voyager-1” will pass it through 16 700 years (approximately 3,59 light years), “pioneer-11” – 18 300 years, “Voyager 2” – 300 in 20 years.
“Pioneer 10” is heading to the small star Ross 248 in the Andromeda constellation 800 and after 33 years will come nearer to it on distance of 3.39 light years.
Further, “Voyager-1” approaching the star TYC 3135-52-1, which is 46.9 light years from the Sun, at a distance of 0.3 parsec (less than one light year). This will happen in about 302 700 years.
Using 3.4 billion years, the probe will reach the stars DR2 Gaia 2091429484365218432 520 light years from Earth.
“The results show how much time is required to fly to the nearest stars with such velocities reached by these spacecraft (about 15 km/s relative to the Sun),” – said the authors of the study.
Earlier it was reported that the spacecraft New Horizons has made the deep space photo in the history of mankind. At this time he was at a distance of 6.05 billion kilometers from Earth.
