A visual band light curve of PZ Cassiopeiae, from AAVSO data [15] In 1956, R. Weber announced his discovery that the star's brightness varies. [16] PZ Cas is a slow semi-regular variable star with the period quoted as 925 days in the General Catalogue of Variable Stars, [17] although periods of 850 and 3,195 days have been derived.
Omicron Cassiopeiae is a triple star and the primary is another γ Cassiopeiae variable. Eta Cassiopeiae (Achird) is the nearest star in Cassiopeia, located some 19.13 ly away. [ 30 ] It is a binary star made up of a G-dwarf star similar to the Sun, of apparent magnitude 3.45, and a K-dwarf star of apparent magnitude 7.51. [ 31 ]

WZ Cassiopeiae (WZ Cas) is a deep red hued star in the northern constellation of Cassiopeia. It is a variable star with a magnitude that ranges from 6.3 down to 8.8, [ 3 ] placing it near the limit of naked eye visibility at peak magnitude.
TZ Cassiopeiae (TZ Cas, HIP 117763, SAO 20912) is a variable star in the constellation Cassiopeia with an apparent magnitude of around +9 to +10. It is approximately 8,400 light-years away from Earth. The star is a red supergiant star with a spectral type of M3 and a temperature around 3,600 K. A light curve for TZ Cassiopeiae, plotted from ...
9 Cassiopeiae (9 Cas) is a white giant star in the constellation Cassiopeia, about 2,370 light years away. 9 Cassiopeiae is classified as an A1 type giant or bright giant . One study noted peculiarities in the spectrum that could indicate a λ Boötis star , [ 9 ] but other researchers have refuted this.
