Theta2 Microscopii (original) (raw)
Theta2 Microscopii (θ2 Mic) is a class A0III (white giant) star in the constellation Microscopium. Its apparent magnitude is 5.76 and it is approximately 390 light years away based on parallax. It is an Ap star, a chemically peculiar star with unusually strong metallic spectral lines. The main star is reported as an astrometric binary, with two components A (6.24 mag) and B (6.88 mag) orbiting with a semimajor axis of 0.836" and eccentricity 0.201, with a period 464.66 years. A more distant companion, C, has a separation around 78.4" and magnitude 10.3.

(en) Theta2 Microscopii (θ2 Microscopii, förkortat Theta2 Mic, θ2 Mic) som är stjärnans Bayerbeteckning, är en dubbelstjärna belägen i den sydöstra delen av stjärnbilden Mikroskopet. Den har en kombinerad skenbar magnitud på 5,76 och är svagt synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallaxmätning inom Hipparcosuppdraget på ca 8,4 mas, beräknas den befinna sig på ett avstånd på ca 390 ljusår (ca 120 parsek) från solen. (sv) Theta2 Microscopii (67 Microscopii) é uma estrela na direção da constelação de Microscopium. Possui uma ascensão reta de 21h 24m 24.80s e uma declinação de −41° 00′ 24.1″. Sua magnitude aparente é igual a 5.76. Considerando sua distância de 463 anos-luz em relação à Terra, sua magnitude absoluta é igual a 0.00. Pertence à classe espectral A0III. (pt) HD203585 — подвійна зоря. Ця подвійна система має видиму зоряну величину в смузі V приблизно 6,3.Вона розташована на відстані близько 463,3 світлових років від Сонця. (uk) |
