HD 47667 is a single [9] star in the southern constellation of Canis Major. It is visible to the naked eye with an apparent visual magnitude of 4.832. [2] The estimated distance to this star, based upon an annual parallax shift of 3.30±0.35 mas, [1] is roughly 1,000 light years. It is moving further away with a heliocentric radial velocity of +29 km/s. [4] The star made its closest approach to the Sun some 8.7 million years ago at a separation of around 362 ly (111.12 pc). [4]
Roughly 40 million years old, [6] this is an evolved K-type giant star with a stellar classification of K2+ IIIa CN0.5 Ca1. [3] The suffix notation indicates overabundances of calcium and the cyanide molecule have been found in the spectrum of the stellar atmosphere. The star has 7.4 [6] times the mass of the Sun and has expanded to 28 [7] times the Sun's radius. It is radiating 2,317 [4] times the Sun's luminosity from its enlarged photosphere at an effective temperature of 4,200 K. [2]
