In the red supergiant star in the place approximately 7,800 light-year away from the sun in the Cassiopeia TZ star the scientific name TZ Cassiopeiae (as for the abbreviated designation TZ Cas). The radius is 400 times of the sun, and it is said that the intensity of light is approximately 98,000 times of the sun. This fixed star is located in Cassiopeia, and is a strange light LC-shaped pulsating variable star doing it between 8.86 and 10.5 [⁸]; [⁹]. This star is done by the variable star synthesis catalogue with a representative star of the LC type [¹⁰].
