Upsilon Tauri (υ Tauri) is a solitary, white-hued star in the zodiac constellation of Taurus, and is a member of the Hyades star cluster. It is faintly visible to the naked eye with an apparent visual magnitude of +4.3. Based upon an annual parallax shift of 21.21 mas seen from Earth, it is around 154 light years from the Sun. (en) Ypsilon Tauri (υ Tauri, förkortat Ypsilon Tau, υ Tau) som är stjärnans Bayerbeteckning, är en ensam stjärna belägen i den mellersta delen av stjärnbilden Oxen och ingår i stjärnhopen Hyaderna. Den har en skenbar magnitud på 4,28 och är synlig för blotta ögat. Baserat på parallaxmätning inom Hipparcosuppdraget på ca 21,2 mas, beräknas den befinna sig på ett avstånd av ca 154 ljusår (47 parsek) från solen. (sv) Upsilon Tauri (69 Tauri) é uma estrela na direção da constelação de Taurus. Possui uma ascensão reta de 04h 26m 18.39s e uma declinação de +22° 48′ 49.3″. Sua magnitude aparente é igual a 4.28. Considerando sua distância de 155 anos-luz em relação à Terra, sua magnitude absoluta é igual a 0.90. Pertence à classe espectral A8Vn. É uma estrela variável δ Scuti e é membro do aglomerado aberto Híades. (pt) 天街增三，即金牛座υ（υ Tau，υ Tauri）是一个位于金牛座的三合星系统。它们距离地球约155光年，是离太阳系最近的疏散星团——毕宿星团的成员。 天街增三的主星天街增三A是一颗白色A-型主序星，平均视星等为+4.28。它是一颗盾牌座δ型变星，视星等在+4.28至+4.31之间变化，光变周期为3.56小时。它同时也是一个分光双星系统，由两颗相距0.02角秒（1AU），视星等分别为+4.4和+6.5等的恒星组成。天街增三C围绕着这个双星系统旋转，距离为110角秒，视星等为12等。 有时候天街增三也和金牛座72一起共用金牛座υ这个名字。金牛座72在天球上和天街增三相距0.29°，但实际上，金牛座72不是毕宿星团的成员，它到地球的距离比毕宿星团的恒星远三倍。 (zh) |
