10 Boötis is a suspected astrometric binary [8] star system in the northern constellation of Boötes, [7] located around 528 light years away from the Sun. It is visible to the naked eye under suitable viewing conditions as a dim, white-hued star with an apparent visual magnitude of 5.76. [2] Its magnitude is diminished by an extinction of 0.17 due to interstellar dust. [9] This system is moving away from the Earth with a heliocentric radial velocity of +6 km/s. [5]
The visible component is an ordinary A-type main-sequence star with a stellar classification of A0 Vs, [4] where the 's' notation indicates "sharp" absorption lines. It is 337 [2] million years old with a moderate rotation rate, showing a projected rotational velocity of 75 km/s. [3] The star has 2.87 [3] times the mass of the Sun and about 2.7 [6] times the Sun's radius. It is radiating 113 [3] times the Sun's luminosity from its photosphere at an effective temperature of 9,441 K. [3]
