Summary
| Description |
English: Approximate paths of Voyager 2 and the star Sirius over the next 296,000 years, viewed from directly above the ecliptic plane. The Sun is in the centre; the yellow Vernal point arrow is ten light years long; Sirius is the white disc at the left (size exaggerated for clarity); the long white diagonal line 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 curve very slightly); the small white and red spots at centre right depict Alpha and Proxima Centauri. |
