Lambda Mensae (λ Men, λ Mensae) is a medium mass orange giant star in the southern constellation Mensa.〔 Though it has the designation Lambda, it is actually the twenty-fourth brightest star in the constellation and not the eleventh. Parallax calculations put this star at a distance of 385 light-years or 118 parsecs. From this and its apparent magnitude of 6.54, it can be said that this star has a luminosity of 27 times that of the Sun (40 times bolometric). The mass of the star is estimated at 1.5 to 3 solar masses and it has a radius of 7.49 solar radii. ==References==
