41 Capricorni is a binary star[8] system in the southern constellation of Capricornus. It is faintly visible to the naked eye with an apparent visual magnitude of +5.24.[2] The distance to this star, based upon an annual parallax shift of Script error: No such module "val".,[1] is around 171 light years. It is moving closer with a heliocentric radial velocity of −45 km/s.[5]
This is a yellow K-type giant star with a stellar classification of K0 III.[4] At the age of around 550 million years[2] it has become a red clump star,[3] which indicates it is generating energy via helium fusion at its core. It has an estimated 2.55 times the mass of the Sun[2] and is radiating 48 times the Sun's luminosity[5] from its photosphere at an effective temperature of 4,910 K.[6] The magnitude 11.5 companion lies at an angular separation of Script error: No such module "val"., as of 2008.[8]
