Delta1 Canis Minoris, Latinized from δ1 Canis Minoris, is a solitary,[11] yellow-white hued star in the constellation Canis Minor. It is faintly visible to the naked eye with an apparent visual magnitude of +5.25.[2] Based upon an annual parallax shift of 4.29 mas as seen from Earth,[1] this star is located roughly 760 light years from the Sun.
Houk and Swift (1999) list a stellar classification of F0 V[4] for Delta1 Canis Minoris, indicating it is an F-type main-sequence star. However, Cowley et al. (1969) gave it a class of F0 III, which would suggest it is instead an evolved giant star.[3] The spectrum displays a higher than solar metallicity – a term indicating the abundance of elements other than hydrogen and helium compared to the Sun. The star is spinning with a projected rotational velocity of 50[9] km/s and is radiating 319[7] times the Sun's luminosity from its photosphere at an effective temperature of 7,623 K.[8]
