The name Heryibwia was discussed and adopted by the IAU WGSN in 2026 for the star designated η Sgr (HR 6832, HD 167618, HIP 89642, WDS J18176-3646A, Gaia DR3 4038055447778237312). The star is a red giant variable star 42 parsecs away with mean apparent V magnitude of 3.11, and Corbally (1984) spectrally classified the star as M3IIIab. Jim Kaler notes that the star is near the tip of the red giant branch and is "either with a dead helium core or having just fired the helium core up to fuse to carbon and oxygen." The star is part of a binary system with a faint, 8th magnitude companion eta Sgr B (HD 167618B, Gaia DR3 4038055447710652032) situated 3.5 arcseconds away, first reported by Sherburne Wesley Burnham in 1879. The binary system is IDed in the Washington Double Star Catalog as BU 760 (WDS J18176-3646). Corbally (1984) classified the companion B as G8:IV:. The binary has advanced approximately 10 degrees since 1879, and widened somewhat (2.8" to 3.5" in 2016). WGSN assigned the name Heryibwia to the A component of the η Sgr system.
