Sorry Ethan, this is not entirely true. While it is true that there is no deliberate target, someone at JPL [sorry, forgot to copy his name down, he deserves the credit] calculated the motions of local stars to 100,000 years. Both Voyagers will pass to around 1 Light-year (approx) of the star AC +79 3888 in about 40,000 years. AC +79 3888 is currently 17 light years away and is expected to be about 3 light years away by that time. [The velocity is left as an excercise to elementary school students...]. ;-) After Neptune encounter of V 2, a decision will be made whether to use the remaining manuveuring fuel to improve the current trajectory for a closer encounter with AC +79 3888. --eugene miya NASA Ames Research Center {hplabs,ihnp4,dual,hao,decwrl,allegra}!ames!aurora!eugene emiya@ames-vmsb
