Gamma Mensae , Latinized from γ Mensae, is an orange-hued star system in the southern constellation of Mensa . The apparent visual magnitude of 5.19[ 2] parallax shift of 7.70 mas as seen from the Earth,[ 1] light years from the Sun . At that distance, the visual magnitude is diminished by an extinction factor of 0.033 due to interstellar dust .[ 9] population II star, but has Sun-like abundances of most elements.[ 11]
This is a probable astrometric binary system[ 4] orbital elements . The visible member, component A, is an evolved K-type giant star with a stellar classification K2 III[ 3] mass as the Sun but has expanded to five times the Sun's radius .[ 9] Sun's luminosity from its enlarged photosphere at an effective temperature of 4,491 K.[ 3]
