e Eridani is a busy and complex system. The star is surrounded by a narrow ring of hot dust in a very close orbit, beyond which lies its planetary system. This consists of at least three (and possibly as many as six) planets, all orbiting at distances that would place them within Earth'sorbit around the Sun. Far beyond these planets, extending between twenty and thirty AU from the star, is a second disc of dust, far more extensive than the narrow inner band around the central star.
The yellowdwarf e Eridani is similar to the Sun in many ways, matching closely in terms of spectrum and size, while being somewhat cooler and less luminous. This image of e Eridani, then, gives some impression of how the Sun would appear if viewed from a distance of approximately twenty light years. Imagery provided by Aladin sky atlas
