Delta Caeli is a solitary,[9] blue-white hued star in the southern constellation of Caelum. Its name is a Bayer designation that is Latinized from δ Caeli, and abbreviated Delta Cae or Delta Cae. This is a dim star but visible to the naked eye, having an apparent visual magnitude of +5.06.[2] Based upon an annual parallax shift of Script error: No such module "val". as seen from Earth,[1] this star is located approximately Script error: No such module "convert". away. At that distance, the visual magnitude is diminished by an extinction factor of 0.13 due to interstellar dust.[5] It is receding from the Sun with a radial velocity of 14 km/s.[4]

This is a B-type star with a stellar classification of B2 IV-V,[3] where the luminosity class IV-V indicates the spectrum shows mixed traits of a subgiant star and a main sequence star. It has 7 times the mass of the Sun and about 4 times the Sun's radius.[1] The star is around nine[7] million years old and is spinning with a projected rotational velocity of 10 km/s.[6] It is radiating 2,075 times the Sun's luminosity from its photosphere at an effective temperature of 19,616 K.[1]
