PZ Cassiopeiae


PZ Cassiopeiae is a red supergiant star located in the Cassiopeia constellation, and a semi-regular variable star.
== Characteristics ==
PZ Cas is an extreme luminous red supergiant star, one of the largest stars currently known with estimates at 1,190–1,940 times the Sun's radius. Its distance from Earth was initially estimated to be around 7800 light-years (2.4 kiloparsecs). Subsequent studies of the star using the water masers that surround it have allowed to refine both the distance and the parameters of this star, deriving a distance of 9,160 light-years (2.81 kiloparsecs) that translates into a luminosity for it of between 240,000 and 270,000 times the Sun's luminosity, a radius 1,260-1,340 the solar one, and an initial mass 25 times that of our star. These parameters are all similar to those estimated for the red hypergiant VY Canis Majoris.
PZ Cas is a slow semi-regular variable star with the period quoted as 925 days in the GCVS, although periods of 850 and 3,195 days have been derived.〔 The visual range is approximate magnitude 8-10, large for this type of variable.〔
