53 Persei is a single [12] variable star in the northern constellation of Perseus. It has the Bayer designation d Persei, while 53 Persei is the Flamsteed designation. The star is visible to the naked eye as a faint, blue-white hued point of light with an apparent visual magnitude of 4.80. [2] It is located approximately 480  light years away from the Sun, as determined from parallax, and is drifting further away with a radial velocity of +7.3 km/s. [6]

This star has a stellar classification of B4IV, [3] and was the prototype of a class of variable stars known as slowly pulsating B stars. [14] It was one of the first mid-B type variable stars in the northern hemisphere to be studied. [5] The star undergoes non-radial pulsations with a primary period of 2.36 days. Observation of the star with the BRITE satellite revealed eight separate frequencies in the star's light curve. [5]

53 Persei is around 50 [8]  million years old with a projected rotational velocity of 15 km/s. [10] It has six [8] times the mass of the Sun and four [7] times the Sun's radius. The star is radiating 780 [7] times the luminosity of the Sun from its photosphere at an effective temperature of 16,720 K. [9]
