Summary[edit]

Description
English: Approximate paths of Voyager 2 and the star Sirius over the next 296,000 years, viewed from slightly above the ecliptic plane and looking towards just anticlockwise of the Vernal point. The Sun is in the centre; the yellow shell has a radius of ten light years centred on the Sun; Sirius is the white disc at the left (size exaggerated for clarity); the long white diagonal line from left to right is about 18 light years long and depicts the proper motion of Sirius for the next 296,000 years; the red arrow depicts the approximate path of Voyager 2 (simplified as a straight line, in reality it would trend slightly steeper and curve very slightly); the small white and red spots right of centre right depict Alpha and Proxima Centauri.
