	On April 15, 2026, IAU Working Group Star Names adopted the name '''Genghe''' for the naked eye star designated σ Boötis (HR 5447, HD 128167, HIP 71284, GJ 557). The star is a main sequence F-type star of apparent V magnitude of 4.47, and lies at a distance of only 15.8 parsecs. Observations by the HOST Survey of the Large Binocular Telescope in 2018 suggest the presence of exozodiacal dust near the habitable zone of the star.<ref>Ertel, S.; et al.
