Indus and Pavo

Still Image (Now)
Animation (30,000 Years)

Of the stars visible to the naked eye, 61 Cygni moves the fastest. The second fastest, Epsilon Indi, is another dim, nearby (11.84 ly) star, slightly hotter and more luminous than 61 Cygni, though still much dimmer and cooler than many, including the Sun. It's less famous than 61 Cygni, in part because of its far-southerly location (in the chart above, only the top third is clearly visible from locations north of 30° north).

Note the star labeled "Gliese 783". Somewhat farther away than Epsilon Indi (19.87 light years), it actually has a higher velocity through space (almost 140 kilometers per second, with respect to the Sun). Unlike Epsilon Indi, which is moving more-or-less across our line of sight, Gliese 783 is moving rapidly towards us. It will gradually close from 19.87 light years to 6.7 light years, in approximately 40,000 years. At that time it will be moving across the sky much faster than either 61 Cygni or Epsilon Indi, and be almost 10 times brighter than it is now. You can see Gliese 783 approach and get brighter as the animation runs.

Several other nearby stars, most of which move somewhat quickly, are identified on the chart above.
