Phi3 Ceti is a solitary,[8] orange-hued star in the equatorial constellation of Cetus. It is faintly visible to the naked eye with an apparent visual magnitude of 5.31.[2] Based upon an annual parallax shift of 6.11 mas as seen from Earth,[1] it is located approximately 530 light years from the Sun, give or take 20 light years. The star is drifting closer with a radial velocity of −25.5 km/s.[1]

This is an evolved K-type giant star with a stellar classification of K5 III.[3] It has about 1.4[5] times the mass and 44[1] times the radius of the Sun. The star radiates 441 times the solar luminosity from its photosphere at an effective temperature of 3,974 K.[1]
