63 Ceti is a star in the constellation of Cetus. With an apparent magnitude of about 5.9, the star is barely visible to the naked eye (see Bortle scale). Parallax estimates made by the Hipparcos spacecraft put it at a distance of about 390 light years (129 parsecs) away from the Earth.
63 Ceti has a spectral type of K0III, implying a K-type giant. 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 11 times larger than the Sun, a mass of about 1.85 times the Sun, and an effective temperature of 4940 K. 63 Ceti is currently at the horizontal branch, an stage in stellar evolution.
