**53 Persei** is a single[13] [variable star](/source/Variable_star) in the northern [constellation](/source/Constellation) of [Perseus](/source/Perseus_(constellation)). It has the [Bayer designation](/source/Bayer_designation) **d Persei**, while *53 Persei* is the [Flamsteed designation](/source/Flamsteed_designation). The star is visible to the naked eye as a faint, blue-white hued point of light with an [apparent visual magnitude](/source/Apparent_visual_magnitude) of 4.8. It is located approximately 480 [light years](/source/Light_year) away from the Sun, as determined from [parallax](/source/Stellar_parallax), and is drifting further away with a [radial velocity](/source/Radial_velocity) of +7.3 km/s.[7]

A [visual band](/source/Photometric_system#Photometric_letters) [light curve](/source/Light_curve) for V469 Persei, plotted from data published by Huang *et al.* (1994)[14]

This star has a [stellar classification](/source/Stellar_classification) of B4IV,[4] and was the prototype of a class of variable stars known as [slowly pulsating B stars](/source/Slowly_pulsating_B_star).[15] It was one of the first mid-B type [variable stars](/source/Variable_star) in the northern hemisphere to be studied.[6] The star undergoes non-radial pulsations with a primary period of 2.36 days. Observation of the star with the [BRITE](/source/BRITE) satellite revealed eight separate [frequencies](/source/Frequencies) in the star's [light curve](/source/Light_curve).[6]

53 Persei is around 50[9] million years old with a [projected rotational velocity](/source/Projected_rotational_velocity) of 15 km/s.[11] It has six[9] times the [mass of the Sun](/source/Mass_of_the_Sun) and four[8] times the [Sun's radius](/source/Sun's_radius). The star is radiating 780[8] times the [luminosity of the Sun](/source/Luminosity_of_the_Sun) from its [photosphere](/source/Photosphere) at an [effective temperature](/source/Effective_temperature) of 16,720 K.[10]
