Image of Ran, or Epsilon Eridani

Among the dustlanes surrounding Ran lurks its companion Ægir, a gas giant planet or possibly a brown dwarf, as shown here.

An orange dwarf star in the northern parts of Eridanus, the River. Ran, perhaps better known by its Bayer designation of Epsilon Eridani, is a faint dwarf star, much less luminous than the Sun, and most notable for its proximity to the Solar System - it is just 10.5 light years away.
