3Eta Cep is a K-type (Orange) star. It carries the designation 3Eta Cep.
3Eta Cep lies approximately 46.5 light-years from Earth, placing it within the Sun's local stellar neighborhood. This relatively short cosmic distance means the light reaching us today departed the star only about 46 years ago.
3Eta Cep is classified as a spectral class K star (K-type (Orange)) on the Harvard spectral classification system.
At an apparent magnitude of +3.41, 3Eta Cep is visible to the naked eye under reasonably clear skies. It may require dark-sky conditions to be seen comfortably in areas with significant light pollution. Observers will note its yellow hue, which corresponds to a B-V color index of +0.912.
