26 Boötis is a single[7] star in the northern constellation of Boötes,[6] located 188 light years away from the Sun.[1] It is visible to the naked eye as a dim, yellow-white hued star with an apparent visual magnitude of 5.91.[2] This object is moving closer to the Earth with a heliocentric radial velocity of −16.5 km/s.[2]

This is an F-type subgiant star with a stellar classification of F2 IV,[3] which suggests it has exhausted the supply of hydrogen at its core and is in the process of evolving into a giant. It is an estimated 1.6[5] billion years old with 1.46[5] times the mass of the Sun and 2.43[1] times the Sun's radius. The star is radiating 11.6[1] times the Sun's luminosity from its photosphere at an effective temperature of 6,826 K.[1] The rotation rate is moderately high, with a projected rotational velocity of 56 km/s.[4] 26 Boötis is a known source of radio emission.[8]
