INTERSTELLAR & FUTURE
Voyager 1 will reach the Oort cloud in about 300 years and take about 30,000 years to pass through it. Though it is not heading towards any particular star, in about 40,000 years, it will pass within 1.6 light-years of the star Gliese 445, which is at present in the constellation Camelopardalis. That star is generally moving towards the Solar System at about 119 km/s (430,000 km/h; 270,000 mph) NASA says that “The Voyagers are destined—perhaps eternally—to wander the Milky Way.
Voyager 2 is expected to enter interstellar space within a few months of 2016, and its plasma spectrometer should provide the first direct measurements of the density and temperature of the interstellar plasma.
Voyager 2 is not headed toward any particular star, although in roughly 40,000 years it should pass 1.7 light-years from the star Ross 248. And if undisturbed for 296,000 years, Voyager 2 should pass by the star Sirius at a distance of 4.3 light-years.
