dbo:abstract	HD 37811 (HR 1958) is a solitary star in the southern constellation Columba. It has an apparent magnitude of 5.44, allowing it to be faintly seen with the naked eye. Parallax measurements place the object at a distance of 382 light years and it is currently approaching with a heliocentric radial velocity of −8.3 km/s. HD 37811 has a stellar classification of G6/8 III — intermediate between a G6 and G8 giant star that is currently on the red giant branch. It has 3 times the mass of the Sun but has expanded to 11.7 times its girth at an age of 440 million years. It shines with a luminosity of 86 L☉ from its enlarged photosphere at an effective temperature of 5,139 K, giving a yellow glow. HD 37811 has a solar metallicity and spins leisurely with a projected rotational velocity of about 2.4 km/s.
