HD 133683 is a single[9] star in the southern constellation of Triangulum Australe. It has a yellow-white hue and is dimly visible to the naked eye with an apparent visual magnitude of +5.76.[1] The distance to this star is approximately 3,600 light-years based on parallax, but it is drifting closer with a radial velocity of −14.7 km/s.[2]
This is a massive supergiant star with a stellar classification of F5Ib.[3] It has around 11[5] times the mass of the Sun and is spinning with a projected rotational velocity of 4.7 km/s.[7] The star has expanded to 79[2] times the radius of the Sun. It is radiating 5,400[2] times the luminosity of the Sun from its photosphere at an effective temperature of 5,567 K.[2]
