29 Persei is the bright star in the center of this optical light image. 31 Persei is the bright star lower and to the left of 29 Persei.

29 Persei is a single[13] star in the northern constellation of Perseus, located approximately 640 light years away from the Sun based on parallax.[1] It is visible to the naked eye as faint, blue-white hued star with an apparent visual magnitude of 5.16.[2] This object is a member of the Alpha Persei Cluster.[14][15]

This is a B-type main-sequence star with a stellar classification of B3 V.[3] During the 1930s it was reported to have a variable radial velocity, but that may instead have been due to instrument error.[16] The star has a high rate of spin, showing a projected rotational velocity of 120 km/s.[11] It has 6.8[7] times the mass of the Sun and about 3.9[8] 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.[6]
