Delta Caeli is a solitary, 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. Based upon an annual parallax shift of as seen from Earth, this star is located approximately away. At that distance, the visual magnitude is diminished by an extinction factor of 0.13 due to interstellar dust. It is receding from the Sun with a radial velocity of 14 km/s.
This is a B-type star with a stellar classification of B2 IV-V, 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. The star is around nine million years old and is spinning with a projected rotational velocity of 10 km/s. It is radiating 2,075 times the Sun's luminosity from its photosphere at an effective temperature of 19,616 K.
