14 Ceti is a single

light years away. It is moving further from the Earth with a heliocentric radial velocity of +11 km/s,[7] having recently come no closer than 178 ly.[6]

Gray (1989) as well as Houk and Swift (1999) have this star classified as an

subgiant star with a class of F5 IV.[12] The absolute magnitude and effective temperature for this star shows that it is entering the Hertzsprung gap, which is occupied by a class of stars that have consumed the hydrogen at their core but have not yet begun hydrogen fusion along a shell surrounding the center.[11]

projected rotational velocity is a relatively low 5 km/s, but the rotation rate is unknown since the axial tilt hasn't been determined.[2]

14 Ceti shows an

Ap star.[11] The activity properties of this star make it more likely to be the latter.[3]
