Distance
V528 Carinae has an apparent visual magnitude of +6.75. It is a distant star but the exact distance is uncertain. The Hipparcos satellite gives a negative annual parallax and is not helpful. Its Carina OB2 membership allows the distance to be estimated at 3,850 light-years.
Characteristic
V528 Carinae is a red supergiant of spectral type M2 Ib with an effective temperature of 3,700 K. It has a radius of 700 solar radii, making it one of the largest stars. In the visible spectrum luminosity is 11,900 times higher than the sun, but the bolometric luminosity considering all wavelengths reaches 81,000 L☉. It loses mass at 0.5×10−9 M☉ per year.
It is classified as a slow irregular variable whose prototype is TZ Cassiopeiae.
