6 Boötis is a binary star[1] system in the northern constellation of Boötes,[2] located around 460 light years away from the Sun.[3] It has the Bayer designation e Boötis; 6 Boötis is the Flamsteed designation.[2] The system is visible to the naked eye as a faint, orange-hued star with an apparent visual magnitude of 4.92.[4] It is moving closer to the Earth with a heliocentric radial velocity of −3 km/s.[4]
This is a single-lined spectroscopic binary system with an orbital period of Template:Convert and an eccentricity of 0.4.[1] The visible component is an evolved giant star with a stellar classification of K4 III.[5] Its measured angular diameter is Template:Val.[6] At the estimated distance of the star, this yields a physical size of about 38 times the radius of the Sun.[7] The star is radiating 430[3] times the luminosity of the Sun from its enlarged photosphere at an effective temperature of 4,050 K.[8] Its companion is probably a low mass red dwarf of around class M8 V.[1]
