VOYAGER 1

Voyager 1 will reach the Oort cloud in about 300 years^[76][77] and take about 30,000 years to pass through it.^[60][71] 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.^[78] That star is generally moving towards the Solar System at about 119 km/s (430,000 km/h; 270,000 mph).^[78] NASA says that “The Voyagers are destined—perhaps eternally—to wander the Milky Way.

VOYAGER 2

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.^[35]

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.^[36] And if undisturbed for 296,000 years, Voyager 2 should pass by the star Sirius at a distance of 4.3 light-years.
