Spacecraft escaping the Solar System

This page shows the current positions and other interesting data of the five spacecraft which are leaving the Solar System on escape trajectories - our first emissaries to the stars. On this scale, the nearest star to the Sun would be approximately 100 meters away, and it would take Voyager 1 about 70,000 years to cover that distance.
