Ran
Epsilon Eridani · Eridanus
Variable starWhat is Ran
Ran is one of the truly nearby stars to the solar system: an orange class-K that pulses with subtle variations just 10.5 light-years away, in the constellation Eridanus. It is so close that the light seen tonight set out little more than a decade ago, a minute distance on the cosmic scale. It takes its name from the Norse goddess of the sea, wife of Aegir, associated with the nets that dragged sailors to the depths: a cold name for a star that may yet harbour worlds of its own.
