'''32 Persei''' is a single<ref name=Eggleton2008/> [[star]] located 149<ref name=GaiaDR2/>&nbsp;[[light year]]s away from the Sun in the northern [[constellation]] of [[Perseus (constellation)|Perseus]].<ref name=SIMBAD/> It has the [[Bayer designation]] of '''l Persei''', while ''32 Persei'' is the [[Flamsteed designation]]. This object is visible to the naked eye as a faint, white-hued star with an [[apparent visual magnitude]] of 4.96.<ref name=XHIP/> It is moving closer to the Earth with a heliocentric [[radial velocity]] of −9&nbsp;km/s,<ref name=Gontcharov2006/> and is a member of the [[Sirius supercluster]]: a stream of stars that share a common motion through space.<ref name=Palous1986/>

This is an ordinary [[A-type main-sequence star]] with a [[stellar classification]] of A3V.<ref name=Cowley1969/> It is around 125<ref name=Meshkat2017/>&nbsp;million years old with a high rate of spin, showing a [[projected rotational velocity]] of 144&nbsp;km/s.<ref name=Zorec2012/> The star has double<ref name=Zorec2012/> the [[mass of the Sun]] and 1.8<ref name=AllendePrieto/> times the [[Sun's radius]]. It is radiating 21<ref name=Zorec2012/> times the [[luminosity of the Sun]] from its [[photosphere]] at an [[effective temperature]] of 8,872&nbsp;K.<ref name=Zorec2012/>
