42 Cassiopeiae is a possible binary star[9] system in the northern circumpolar constellation of Cassiopeia. It is visible to the naked eye as a dim, blue-white hued star with a baseline apparent visual magnitude of +5.18. The system is located approximately 293 light years from the Sun based on parallax, and is drifting further away with a radial velocity of +7 km/s.

This is classified as a suspected eclipsing binary of the Algol type,[5] with a period of 16.77 days and a magnitude decrease of 0.3.[10] The primary is a B-type main-sequence star with a stellar classification of B9V.[4] It is roughly 67[7] million years old and is spinning with a projected rotational velocity of 149 km/s.[3] The star has 2.7[3] times the mass of the Sun and 2.6[6] times the Sun's radius. It is radiating 66[1] times the luminosity of the Sun from its photosphere at an effective temperature of 10,141 K.[6]
