18 Boötis is a single[9] star in the northern constellation of Boötes,[8] located about 85 light years away from the Sun.
[1] It is visible to the naked eye as a faint, yellow-white hued star with an apparent visual magnitude of 5.41.
[2] This object is a suspected member of the Ursa Major Moving Group, based on velocity criteria.
[13] 18 Boötis is an estimated 1.15[4] billion years old and is spinning with a projected rotational velocity of 40.5 km/s.
The star is radiating 3.9[2] times the luminosity of the Sun from its photosphere at an effective temperature of 6,731 K.[4] An infrared excess has been detected that suggests a cold debris disk is orbiting 34.9 AU from the host star with a blackbody temperature fit of 65 K.[5]
