Delta Volantis, Latinized from δ Volantis, is a solitary[11] star in the southern constellation Volans. It has an apparent visual magnitude of +3.97, which is bright enough to be seen with the naked eye. Based upon parallax measurements, is approximately 740 light years from the Solar System.

This is an F-type bright giant star with a stellar classification of F6 II. It has five times Sun's mass,[5] an estimated radius 36 times that of the Sun, and shines with more than a thousand times the Sun's luminosity.[5] The outer atmosphere has an effective temperature of 5,637 K,[8] giving it a yellow hue.[12]
