10 Boötisis a suspectedastrometric binary[8]starsystem in the northernconstellationofBoötes,[7]located around 528light yearsaway from the Sun. It is visible to the naked eye under suitable viewing conditions as a dim, white-hued star with anapparent visual magnitudeof 5.76.[2]Its magnitude is diminished by anextinctionof 0.17 due tointerstellar dust.[9]This system is moving away from the Earth with a heliocentricradial velocityof +6 km/s.[5]
The visible component is an ordinaryA-type main-sequence starwith astellar classificationof A0 Vs,[4]where the 's' notation indicates "sharp"absorption lines.It is 337[2]million years old with a moderate rotation rate, showing aprojected rotational velocityof 75 km/s.[3]The star has 2.87[3]times themass of the Sunand about 2.7[6]times theSun's radius.It is radiating 113[3]times theSun's luminosityfrom itsphotosphereat aneffective temperatureof 9,441 K.[3]
