29 Persei is a single star in the northern constellation of Perseus, located approximately 640 light years away from the Sun based on parallax.

This is a B-type main-sequence star with a stellar classification of B3 V. 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.
