Traveling through space, Voyager-1, Voyager-2 and Pioneer-11 will reach the vicinity of Proxima Centauri, the star closest to our Sun, in 16,000 years. An expert from NASA's Jet Propulsion Laboratory, David Farnochchia and Korin Beyler-Jones from the Max Planck Institute in Germany, told us what other luminaries the vehicles listed could come close to during their epic journey.
Experts calculated that Voyager-1, launched in 1977, which had already moved 140 A away from Earth, would be in 16700 years from Proxima Centauri at a distance of just 3.59 light years. The next target will be the star 3135-52-1, with which the American automatic station will come closer after 302700 years, and fly straight to Gaia DR2 2091429484365218432, located 520 light years from our own star.
Voyager 2 (launched in 1977) and Pioneer 11 (launched in 1973) will also get close to Proxima Centauri first, and then fly to the star Ross-248 from the constellation Andromeda.
“These data clearly show the enormous amount of time that space travel has taken over long distances, taking into account the technologies that we now have,” said Korin Beiler-Jones.
He noted that the impetus for mapping the motion of spacecraft in interstellar space were attempts to understand the orbit of the acclaimed Oumuamua – the first interstellar object in history recorded on the territory of the Solar System.
Based on the data that the specialists managed to get to date, Oumuamua arrived to us from the edges of Vega – the brightest star in the constellation Lyra. The mysterious asteroid moves along a hyperbolic trajectory, and is currently close to the outer edge of our star system, so there is no way to observe it. NASA experts say that Oumuamua is far from the only interstellar guest in the solar system: similar objects arrive to us about once a year, but because of the small size, astronomers haven't come across to this day.
