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]
