12 Boötis
12 Boötis is a spectroscopic binary in the constellation Boötes. It is approximately 122 light years from Earth.
The primary component, 12 Boötis A, is a yellow-white F-type subgiant with an apparent magnitude of +4.82. The spectroscopic binary pair completes one orbit around its centre of mass once every 9.6045 days, with an estimated separation of 0.0035". A companion, 12 Boötis B, was reported with a separation of approximately one arcsecond in 1989, but subsequent surveys have repeatedly failed to detect this companion.
