14 Eridani is a star in the equatorial Eridanus constellation. It has an apparent visual magnitude of 6.143[2] and is moving closer to the Sun with a radial velocity of around −5 km/s.[4] The measured annual parallax shift is Script error: No such module "val".,[1] which provides an estimated distance of about 121 light years. Proper motion studies indicate that this is an astrometric binary.[9][10]
The visible component has a stellar classification of F5 V Fe−0.7 CH−0.5,[3] which indicates it has the spectrum of an F-type main-sequence star with mild underabundances of iron and methylidyne. It is 1.4[6] billion years old with 1.3[6] times the mass of the Sun and 1.5[1] times the Sun's radius. The star is radiating 3.87[1] times the luminosity of the Sun from its photosphere at an effective temperature of 6,719 K.[6] The system has been detected as a source of X-ray emission.[11]
