Zeta Caeli is an orange-hued star in the southern constellation of Caelum. Its name is a Bayer designation that is Latinized from ζ Caeli, and abbreviated Zeta Cae or ζ Cae. With an apparent visual magnitude of +6.36,[3] it is near the lower limit of brightness for stars visible to the naked eye. Based upon an annual parallax shift of Script error: No such module "val". as seen from Earth,[2] this star is located about Script error: No such module "convert". away. It is drifting further from the Sun with a line of sight velocity of +7 km/s.[5]

This is an evolved K-type giant star with a stellar classification of K0 III.[4] At an estimated 414 million years of age, this star has 2.9 times the mass of the Sun but it has expanded to 12 times the Sun's radius. It is radiating 87 times the luminosity of the Sun from its enlarged photosphere at an effective temperature of 4,992 K.[2] This star is a member of the Milky Way's thick disk population.[6]
