p Eridani is a binary star system in the constellation of Eridanus (the River) whose distance from the Sun is 26.7 light-years based upon parallax. It was found to be a double star in December 1825 by James Dunlop in Australia at his home at Paramatta, now spelt Parramatta. It is visible to the naked eye as a dim, orange-hued star. The system is moving further from the Earth with a heliocentric radial velocity of about +20 km/s.
This system consists of a pair of near identical K-type main-sequence stars with stellar classifications of K2V. Component A has visual magnitude 5.87, while component B is magnitude 5.76. They orbit each other with a period of 475.2 years, an eccentricity of 0.53, and a semimajor axis of 7.8″.
