Epsilon Eridani

Definition

Astronomy

  • Star which is a near neighbour of the Sun, at about 10.5 light years, and which seems to be accompanied by a planet several times as large as Jupiter. A K2 type star, smaller and cooler than the Sun. Epsilon Eridani’s possible planet was surmised from an apparent gravitational ‘wobble’ in Epsilon Eridani’s proper motion, but remains contentious, like the possible planet of Barnard’s Star.
