This object is visible to the naked eye as a white-hued star with an apparent visual magnitude of 4.94. It is moving closer to the Earth with a heliocentric radial velocity of −7 km/s. This star has a stellar classification of A0 III, matching that of an A-type giant star. It has a relatively high rate of spin with a projected rotational velocity of 154 km/s. The star is radiating 213 times the Sun's luminosity from its photosphere at an effective temperature of commas 9994 K. References HD 40409 2018-07-16 Kostjuk N. D.
