64 Ceti is a star located located in the constellation Cetus. Based on its spectral type of G0IV, it is a G-type star that has left the main sequence and evolved into a subgiant. It is located 42.02abbr=offNaNabbr=off away, based on a parallax measured by Gaia DR3, and it is moving towards Earth at a velocity of 19km/s. The apparent magnitude of 64 Ceti is 5.62, which makes it visible to the naked eye only in dark skies, far away from light pollution.[1]
64 Ceti is a G-type star that has left the main sequence and now evolved into a subgiant, based on its spectral type of G0IV. It has about 1.53 times the Sun's mass and has expanded to 2.53 times the Sun's diameter.[2] It is emitting 8.13 times the solar luminosity from its photosphere at an effective temperature of 6,066 K. The age of 64 Ceti is estimated at 2.63 billion years, about 58% of the Solar System's age, and it rotates under its axis at a speed of 8.96 km/s, translating into a rotation period of 15 days. The B-V index of the star is 0.52, corresponding to a yellow-white hue of a late G/early F star.
It is located in the constellation Cetus, based on its celestial coordinates. Gaia DR3 measured a parallax of 23.8 milliarcseconds for this star, translating into a distance of 42.02lk=onNaNlk=on. The apparent magnitude of 64 Ceti is 5.62, which means that it is a faint star, visible to the naked eye only from locations with dark skies. The absolute magnitude, i.e. its brightness if it was seen at a distance of 10pc, is 2.49. The star is moving towards Earth at a velocity of 19 km/s. It has a high proper motion across the sky and belongs to the thin disk population, being located 31.03pc above the galactic plane.
