1 Cassiopeiae is a single[10] star in the northern constellation of Cassiopeia, located around 1,130 light years from the Sun.[2] It is visible to the naked eye as a faint, blue-white hued star with an apparent visual magnitude of +4.84.[1] This object is moving closer to the Earth with a heliocentric radial velocity of −9 km/s.[1]

The stellar classification of 1 Cassiopeiae is B0.5 III,[3] matching an evolved B-type giant star. It is 5.7[8] million years old with a projected rotational velocity of 31.[7] The star has 13.1[4] times the mass of the Sun and 10.2[5] times the Sun's radius. It is radiating 18,200[4] times the Sun's luminosity from its photosphere at an effective temperature of 27,200 K.[4]
