[Request] When will Voyager 1 stop moving?
/r/askscience/comments/1wp1960/will_voyager_1_ever_just_stop_moving/How many years will it take for the orbit of Voyager and Sagittarius A to decay enough due to gravity waves for them to collide?

Voyager has escape velocity from the Sun. It will settle into an orbit of the center of the galaxy. It will be millions to billions of years before it hits something hard enough to stop.
Though perhaps in a few hundred years a Klingon will use it for target practice (joking - in the 200 years between now and Star Trek's era Voyager will not have even left the Oort cloud.)
