Phi Eridani is a star in the constellation Eridanus. Its apparent magnitude is 3.57.[2] Located around 47.13 parsecs (153.7 ly) distant,[1] it is between the classifications a blue main-sequence star and subgiant with a spectral type B8IV-V. It is possible that a nearby G-type star is related,[4] and the naked-eye star Eta Horologii may be related as well.[5]
