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 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.
Characteristics.
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. 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 . 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 , 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 above the galactic plane.
