Star in the constellation Cetus
1 Ceti is a star in the constellation of Cetus. With an apparent magnitude of about 6.2,[2] the star is barely visible to the naked eye (see Bortle scale). Parallax estimates put it at a distance of about 535 light-years (164 parsecs) away from the Earth. It is moving further from the Sun with a heliocentric radial velocity of 4 km/s.[5]
This star has a spectral type of K1III,[3] 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.[9] The "CNII" in its spectral type indicates strong cyanogen signature in its outer atmosphere.[10][11] The star is radiating 144[6] times the Sun's luminosity from its enlarged photosphere.
