The Voyager I “space probe” travels about 335 million miles per year. At that rate, it would be 40,000 years before it would come close to another star—“close” meaning within 1.7 light years (almost 10 trillion miles), still too far away to be of any significance. It would take another 37,000 years (a total of 77,000 years since leaving Earth) to reach Alpha Centauri, the nearest star system in our galaxy where there might be some planets that could be checked for evidence of life.
