SIMBAD data

16 Persei is a single, [12] suspected variable star [6] in the northern constellation of Perseus, located approximately 121 light years away based on parallax. [1] It is visible to the naked eye as a yellow-white hued star with an apparent visual magnitude of 4.22. [2] This object is moving further from the Earth with a heliocentric radial velocity of +14 km/s. [7] It displays a relatively high proper motion, traversing the celestial sphere at the rate of 0.224″ per year. [13]

Based upon a stellar classification of F2 III, [3] this matches an aging giant star that has exhausted the hydrogen at its core and is evolving away from the main sequence. It is a possible pulsating Delta Scuti variable, although there is some uncertainty about this classification. [6] However, Kunzli and North (1998) found no variation. [14] The star is 1.44 [8]  billion years old with 1.8 [8] times the mass of the Sun and 3.2 [9] times the Sun's radius. It shows a high rotation rate with a projected rotational velocity of 149 km/s, [3] which is causing an equatorial bulge that is an estimated 24% larger than the polar radius. [15] 16 Persei is radiating 23 [2] times the Sun's luminosity from its photosphere at an effective temperature of 7,004 K. [10]

It has two reported visual companions: B, with magnitude 12.8 and separation 76.7", and C, with magnitude 10.43 and separation 234". [16]
