14 Boötis is a possible binary star[9] system located 110 light years away from the Sun in the northern constellation of Boötes. It is visible to the naked eye as a dim, yellow-white hued star with a combined apparent visual magnitude of 5.53.[2] This system is moving closer to the Earth with a heliocentric radial velocity of −40 km/s.[4] It has a relatively high proper motion, traversing the celestial sphere at the rate of 0.260 arc seconds per annum.[10]

The component of this system remain unresolved as of 2002;[11] Eggleton and Tokovinin (2008) listed an angular separation of Script error: No such module "val"..[9] The visible component is an F-type main-sequence star with a stellar classification of F8 V[3] There are enhanced barium lines in the star's spectrum, but these are likely caused by regions of photospheric activity rather than being a barium star.[12] It is 2.6[4] billion years old and is spinning with a projected rotational velocity of 5.6 km/s,[7] giving it a rotation period of 26 days.[6]

14 Boötis has 1.46[4] times the mass of the Sun and 2.1[1] times the Sun's radius. It is radiating 5.9[1] times the luminosity of the Sun from its photosphere at an effective temperature of 6,169 K.[1] The metallicity is near solar, based on the abundance of iron in the stellar atmosphere.[6]
