24 Lyncis is a single [8] star in the northern constellation of Lynx. It is visible to the naked eye as a dim, white-hued star with an apparent visual magnitude of 4.96. [1] The distance to this star, as determined from its parallax measurements, is around 274 light years. [1] It is moving further away from the Earth with a heliocentric radial velocity of about +9 km/s. [2]
This object has a stellar classification of A3 IVn, [3] matching an A-type star with a subgiant luminosity class. The 'n' suffix indicates "nebulous" absorption lines due to rapid rotation. The star is spinning with a projected rotational velocity of 233 km/s, [6] giving it an equatorial bulge that is 17% larger than the polar radius. [9] Zorec et al. (2012) estimate the star is actually 88% of the way through its main sequence lifetime. [6] It is 262 [4] million years old with 1.89 [4] times the mass of the Sun. 24 Lyncis is radiating 61 [2] times the luminosity of the Sun from its photosphere at an effective temperature of 8,786 K. [4]
There is a magnitude 11.15 visual companion at an angular separation of 55 ″ along a position angle of 324°, as of 2010. [10]
