- BX Boötis is a star in the northern constellation of Boötes. It is a dim star near the lower limit of visibility to the naked eye, having a nominal apparent visual magnitude of 6.35. Based upon an annual parallax shift of 10.81 mas, it is located 302 light years away. At that distance, the visual magnitude of the star is diminished by an extinction of 0.13 due to interstellar dust. It is moving closer with a heliocentric radial velocity of −11 km/s. This is a magnetic CP star with a stellar classification of A0 Vsp SiSrCr, indicating this is an A-type main-sequence star. The spectrum has very weak lines of helium but displays strong overabundances of silicon and all of the heavier elements except nickel. It is classified as an Alpha² Canum Venaticorum variable with a magnitude that varies from 6.33 to 6.41 over a period of 2.88756 days. BX Boötis is 235 million years old with a projected rotational velocity of 30 km/s. It has 2.7 times the mass of the Sun and 2.5 times the Sun's radius. The star is radiating around 72 times the Sun's luminosity from its photosphere at an effective temperature of 9,164 K. (en)
