It shows emission lines in its spectrum and is classified as a Be star. It shows slight variations in its brightness, between magnitudes 5.54 and 5.59. At an age of 218 million years, 10 Cassiopeiae has expanded away from the main sequence after exhausting its core hydrogen and now has a radius about eight times that of the Sun. With an effective temperature of about commas 11,000 K, it emits nearly a thousand times the luminosity of the Sun. References 431696822314371456 Anderson E. Francis Ch.
