It is visible to the naked eye as faint, blue-white hued star with an apparent visual magnitude of 5.16. This object is a member of the Alpha Persei Cluster.{{citation | title=The Pleiades and alpha Persei Clusters | last1=Eggen | first1=Olin J. | journal=The Astronomical Journal | volume=116 | issue=4 | pages=1810–1815 | date=October 1998 | doi=10.1086/300533 | bibcode=1998AJ....116.1810E | doi-access=free }}{{citation | title=Stellar Membership and Dusty Debris Disks in the α Persei Cluster | last1=Zuckerman | first1=B. | last2=Melis | first2=Carl | last3=Rhee | first3=Joseph H. | last4=Schneider | first4=Adam | last5=Song | first5=Inseok | display-authors=1 | journal=The Astrophysical Journal | volume=752 | issue=1 | id=58 | pages=12 | date=June 2012 | doi=10.1088/0004-637X/752/1/58 | bibcode=2012ApJ...752...58Z | arxiv=1204.3950 | s2cid=119207634 | postscript=. }}
This is a B-type main-sequence star with a stellar classification of B3 V. During the 1930s it was reported to have a variable radial velocity, but that may instead have been due to instrument error.{{citation | title=Radial Velocities and Spectral Types of Some Bright Blue Stars in the Old Open Cluster M67 | last1=Pesch | first1=Peter | journal=Astrophysical Journal | volume=148 | page=781 | date=June 1967 | doi=10.1086/149201 | bibcode=1967ApJ...148..781P | doi-access=free }} The star has a high rate of spin, showing a projected rotational velocity of 120 km/s. It has 6.8 times the mass of the Sun and about 3.9 times the Sun's radius. 29 Persei is radiating 960 times the Sun's luminosity from its photosphere at an effective temperature of 16,143 K.
