Delta3 Canis Minoris, Latinized from δ3 Canis Minoris, is a solitary,[10] white-hued star in the equatorial constellation of Canis Minor. Based upon a parallax of Script error: No such module "val". as seen from Gaia spacecraft in its repeated orbits around the Sun, just beyond the Earth. This star is about 730 light years from the Solar System. At that distance, the visual magnitude of these stars is diminished by an extinction of more than 0.15 due to interstellar dust.[6] With an apparent visual magnitude of +5.81,[2] it is just bright enough to be faintly visible to the naked eye.
This is a B-type main-sequence star with a stellar classification of B9 V.[3] It is about Script error: No such module "val". of the way through its main sequence lifetime and is spinning rapidly with a projected rotational velocity of 259 km/s.[7] The star has an estimated 3.16[7] times the mass of the Sun and about 2.1[8] times the Sun's radius. It is radiating 175 times the Sun's luminosity from its photosphere at an effective temperature of 9,908 K.[7]
