63 Ceti is a star in the constellation of Cetus, located just over a degree south of the celestial equator. With an apparent magnitude of about the star is barely visible to the naked eye (see Bortle scale) as a dim, orange-hued point of light. Parallax estimates put it at a distance of about 378 light years (116 parsecs) away from the Earth, and it is drifting further away with a radial velocity of km/s.
63 Ceti has a spectral type of K0III, implying an aging K-type giant star. These types of stars are generally reddish-colored stars with spectral types from K to M, with radii that are 10 to 100 times larger than the Sun. 63 Ceti fits this description, with a radius about times larger than the Sun, a mass of about times the Sun, and an effective temperature of K. 63 Ceti is a red clump giant, indicating it is currently at the horizontal branch, a stage in stellar evolution, and is generating energy through core helium fusion. It is close to a billion years old and is radiating times the luminosity of the Sun from its photosphere at an effective temperature of K.
