			Beta Trianguli was originally listed as a A5III (giant luminosity class) in the Morgan-Keenan (1943) and Johnson-Morgan (1953) compilations of MK spectral type standard stars. It is a bright (V=3.00 mag) star at distance 39 parsecs, and was among the most luminous stars with a dusty debris disk resolved by the Herschel Space Observatory (Pawellek et al. 2014).
