TZ Cassiopeaie (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 below 4,000 K. The initial mass of TZ Cassiopeiae has been estimated from its position relative to theoretical stellar evolutionary tracks to be around 15 M☉.

rdfs:comment	カシオペヤTZ星（TZ Cassiopeaie、TZ Cas）は、太陽から約7800光年離れたところにある赤色超巨星。半径は太陽の800倍あり、光度は太陽の約98,000倍あるとされている。この恒星はカシオペヤ座に位置しており、8.86等と10.5等の間を変光するLC型の脈動変光星でもある。変光星総合カタログではこの星はLC型の代表星とされている。 (ja) TZ Cassiopeiae (TZ Cas / HIP 117763 / SAO 20912) és un estel variable a la constel·lació de Cassiopea de magnitud aparent mitjana +9,04. Molt allunyada del sistema solar, s'estima que està a una distància de 2.378 parsecs (7.750 anys llum), però l'error en la mesura és de ± 658 parsecs. TZ Cassiopeiae està catalogada com una variable irregular de tipus LC i de fet és prototip d'aquesta subclasse. La seva lluentor varia entre magnitud +8,86 i +10,50 havent-se detectat un possible període de 3.100 dies.

TZ Cassiopeiae, TZ Cas, HIP 117763, SAO 20912) — переменная звезда в созвездии Кассиопеи. Видимая звёздная величина находится в пределах от +9 до +10. Расположена в 8000 световых лет от Солнца. Является красным сверхгигантом спектрального класса M3 с температурой менее 4000 K. Начальную массу TZ Кассиопеи оценили на основе её положения относительно теоретических эволюционных треков, предположительное значение массы составляет около 15M⊙. (ru)
