rdfs:comment
Delta Tauri3 (δ3 Tauri , förkortat Delta3 Tau, δ3 Tau) som är stjärnans Bayerbeteckning, är en dubbelstjärna belägen i den mellersta delen av stjärnbilden Oxen. Den har en kombinerad skenbar magnitud på 4,32 och är synlig för blotta ögat. Baserat på parallaxmätning inom Hipparcosuppdraget på ca 22,0 mas, beräknas den befinna sig på ett avstånd av ca 149 ljusår (46 parsek) från solen. 毕宿二，即金牛座δ³（δ³ Tau，δ³ Tauri）是一颗位于金牛座的三合星系统，它是离太阳系最近的疏散星团——毕宿星团的成员之一，距离地球约148光年，在天球上距离金牛座δ¹0.72°。由于毕宿二的位置接近黄道，故经常被月球所遮掩。此外，太阳系的行星如水星与金星等也有可能遮掩它，但这现象非常罕见。 毕宿二的主星毕宿二A是一颗白色A-型次巨星，它也是一颗猎犬座α²型变星，平均视星等为+4.30，视星等在+4.29至+4.32之间变化，光变周期为57.25天。它的伴星毕宿二B亮度8等，距离主星1.4角秒（64AU）。另一颗伴星毕宿二C，距离主星77角秒，亮度11等。 在中国古代星官系统中，毕宿二属于西方白虎七宿中毕宿第二星，这也是毕宿二名字的来由。它的西方传统名字为Cleeia或Kleeia ，来自希腊语Κλεεια，是Hyades的姐妹。 Delta3 Tauri (δ3 Tauri) is a binary star system in the zodiac constellation of Taurus. Based upon an annual parallax shift of 21.96 mas as seen from Earth, it is located roughly 149 light years distant from the Sun. It is visible to the naked eye with a combined apparent visual magnitude of +4.32. δ3 Tauri is separated from δ1 Tauri by 0.72° on the sky. This star also has the traditional Latin name Cleeia, from the Greek Kleeia (transliteration of Κλεεια), who was one of the Hyades sisters. It is considered a member of the Hyades cluster. δ³ Tauri​ es un sistema estelar triple de la constelación del toro. A una distancia de 148 años luz, está separada angularmente de δ¹ Tauri por 0.72°. Esta estrella tradicionalmente tiene el nombre de origen griego (griego Κλεεια) que se translitera como Cleeía o Kleeía que es una de las hermanas híadas.​ El primer componente δ³ Tauri A, es una estrella blanca tipo A subgigante con una magnitud aparente de +4.30. Hay una tercera componente, de undécima magnitud y situada a 77 segundos de arco, se trata de δ³ Tauri C. HD27962 — подвійна зоря. Ця подвійна система має видиму зоряну величину в смузі V приблизно 4,3.Вона розташована на відстані близько 147,9 світлових років від Сонця. Delta3 Tauri (68 Tauri) é uma estrela na direção da constelação de Taurus. Possui uma ascensão reta de 04h 25m 29.32s e uma declinação de +17° 55′ 40.8″. Sua magnitude aparente é igual a 4.30. Considerando sua distância de 148 anos-luz em relação à Terra, sua magnitude absoluta é igual a 1.02. Pertence à classe espectral A2IV. É uma estrela variável alpha2 Canum Venaticorum. É membro do aglomerado aberto Híades. 68 Tauri, nota anche come δ3 Tauri, è una stella bianca di sequenza principale di magnitudine +4,30, situata nella costellazione del Toro. È una variabile Alfa2 Canum Venaticorum, di classe spettrale variabile fra A2IV e A1V. Fa parte dell'ammasso aperto delle Iadi. Si tratta in realtà di un sistema stellare multiplo distante circa 148 anni luce dal sistema solare.

68 Tauri, nota anche come δ3 Tauri, è una stella bianca di sequenza principale di magnitudine +4,30, situata nella costellazione del Toro. È una variabile Alfa2 Canum Venaticorum, di classe spettrale variabile fra A2IV e A1V. Fa parte dell'ammasso aperto delle Iadi. Si tratta in realtà di un sistema stellare multiplo distante circa 148 anni luce dal sistema solare. HD27962 — подвійна зоря. Ця подвійна система має видиму зоряну величину в смузі V приблизно 4,3.Вона розташована на відстані близько 147,9 світлових років від Сонця. Delta3 Tauri (δ3 Tauri) is a binary star system in the zodiac constellation of Taurus. Based upon an annual parallax shift of 21.96 mas as seen from Earth, it is located roughly 149 light years distant from the Sun. It is visible to the naked eye with a combined apparent visual magnitude of +4.32. δ3 Tauri is separated from δ1 Tauri by 0.72° on the sky. This star also has the traditional Latin name Cleeia, from the Greek Kleeia (transliteration of Κλεεια), who was one of the Hyades sisters. It is considered a member of the Hyades cluster. In Chinese, 畢宿 (Bì Xiù), meaning Net, refers to an asterism consisting δ3 Tauri, ε Tauri, δ1 Tauri, γ Tauri, Aldebaran, 71 Tauri and λ Tauri. Consequently, the Chinese name for δ3 Tauri itself is 畢宿二 (Bì Xiù èr), "the Second Star of Net". The magnitude 4.35 primary, component A, appears to be an A-type subgiant star with a stellar classification of A2 IV. It is a candidate blue straggler and shows characteristics of an Am star. Abt (1985) gave it a classification of A2kA3hA5m, indicating that the spectrum displays the calcium K-line of an A2 star, the hydrogen lines of an A3 star and the metal lines of an A5 star. It is deficient in scandium but has enhanced iron peak and heavy elements. Although suspect of variability in the past, Delta3 Tauri A was subsequently determined to be photometrically constant. The companion, component B, is a magnitude 8.37 star at an angular separation of 1.80 arc seconds along a position angle of 341°, as of 2010. At 77 arcseconds away (as of 2006) is a magnitude 11.12 visual companion, designated component C. Delta Tauri3 (δ3 Tauri , förkortat Delta3 Tau, δ3 Tau) som är stjärnans Bayerbeteckning, är en dubbelstjärna belägen i den mellersta delen av stjärnbilden Oxen. Den har en kombinerad skenbar magnitud på 4,32 och är synlig för blotta ögat. Baserat på parallaxmätning inom Hipparcosuppdraget på ca 22,0 mas, beräknas den befinna sig på ett avstånd av ca 149 ljusår (46 parsek) från solen. δ³ Tauri​ es un sistema estelar triple de la constelación del toro. A una distancia de 148 años luz, está separada angularmente de δ¹ Tauri por 0.72°. Esta estrella tradicionalmente tiene el nombre de origen griego (griego Κλεεια) que se translitera como Cleeía o Kleeía que es una de las hermanas híadas.​ El primer componente δ³ Tauri A, es una estrella blanca tipo A subgigante con una magnitud aparente de +4.30. Además, se trata de una estrella variable de la clase Alfa-2 Canum Venaticorum variando su brillo de forma intrínseca de tal manera que es observable diferencias de su magnitud aparente entre +4.29 y +4.32, apenas perceptibles a simple vista y con un periodo de 57.25 días. Su compañera más cercana no es visible a simple vista, tiene magnitud 8 y es su acompañante binaria δ³ Tauri B a 1,4 segundos de arco lo que hace suponer que la distancia física entre ambas sea de al menos 64 UA. Hay una tercera componente, de undécima magnitud y situada a 77 segundos de arco, se trata de δ³ Tauri C. Delta3 Tauri (68 Tauri) é uma estrela na direção da constelação de Taurus. Possui uma ascensão reta de 04h 25m 29.32s e uma declinação de +17° 55′ 40.8″. Sua magnitude aparente é igual a 4.30. Considerando sua distância de 148 anos-luz em relação à Terra, sua magnitude absoluta é igual a 1.02. Pertence à classe espectral A2IV. É uma estrela variável alpha2 Canum Venaticorum. É membro do aglomerado aberto Híades. 毕宿二，即金牛座δ³（δ³ Tau，δ³ Tauri）是一颗位于金牛座的三合星系统，它是离太阳系最近的疏散星团——毕宿星团的成员之一，距离地球约148光年，在天球上距离金牛座δ¹0.72°。由于毕宿二的位置接近黄道，故经常被月球所遮掩。此外，太阳系的行星如水星与金星等也有可能遮掩它，但这现象非常罕见。 毕宿二的主星毕宿二A是一颗白色A-型次巨星，它也是一颗猎犬座α²型变星，平均视星等为+4.30，视星等在+4.29至+4.32之间变化，光变周期为57.25天。它的伴星毕宿二B亮度8等，距离主星1.4角秒（64AU）。另一颗伴星毕宿二C，距离主星77角秒，亮度11等。 在中国古代星官系统中，毕宿二属于西方白虎七宿中毕宿第二星，这也是毕宿二名字的来由。它的西方传统名字为Cleeia或Kleeia ，来自希腊语Κλεεια，是Hyades的姐妹。
