Tau8 Serpentis, Latinized from τ8 Serpentis, is an A-type main sequence star in the constellation of Serpens, approximately 320 light-years from the Earth. It has an apparent visual magnitude of approximately 6.144. Although it was observed to be binary by speckle interferometry in 1985, subsequent observations show no sign of binarity, and the detection appears to have been spurious.

(en) Tau8 Serpentis (τ8 Serpentis, förkortat Tau8 Ser, τ8 Ser) som är stjärnans Bayerbeteckning, är en ensam stjärna belägen i den mellersta delen av stjärnbilden Ormen, i den del som representerar ”ormens huvud” (Serpens Caput). Den har en skenbar magnitud på 6,14 och är svagt synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallaxmätning inom Hipparcosuppdraget på ca 10,2 mas, beräknas den befinna sig på ett avstånd på ca 320 ljusår (ca 20 parsek) från solen. (sv) Tau8 Serpentis (26 Serpentis) é uma estrela na direção da constelação de Serpens. Possui uma ascensão reta de 15h 44m 42.15s e uma declinação de +17° 15′ 51.2″. Sua magnitude aparente é igual a 6.15. Considerando sua distância de 321 anos-luz em relação à Terra, sua magnitude absoluta é igual a 1.18. Pertence à classe espectral A0V. (pt)
