Omega2 Aquilae, Latinized from ω2 Aquilae, is the Bayer designation for a star in the equatorial constellation of Aquila, the eagle. It has an apparent visual magnitude of 6.0, which is close to the lower limit of detectability with the naked eye. According to the Bortle Dark-Sky Scale, this star can be viewed from dark rural skies. As the Earth orbits about the Sun, this star undergoes a parallax shift of 11.7 mas. This is equivalent to a physical distance of 279 light-years (86 parsecs) from Earth, give or take a 2 light year margin of error. The star is drifting closer to the Sun with a radial velocity of −26 km/s.

  • Omega² de l'Àguila (Ω² Aquilae) és una nana de la seqüència principal blanca del tipus A de la magnitud aparent +6,03. Està aproximadament a 279 anys-llum de la Terra. (ca)
  • Omega2 Aquilae (ω2 Aqulilae, förkortat Omega2 Aql, ω2 Aql) är en ensam stjärna belägen i den nordvästra delen av stjärnbilden Örnen. Den har en skenbar magnitud på 6,02 och är svagt synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallaxmätning inom Hipparcosuppdraget på ca 12,3 mas, beräknas den befinna sig på ett avstånd på ca 270 ljusår (ca 81 parsek) från solen. (sv)
  • Omega2 Aquilae (29 Aquilae) é uma estrela na direção da constelação de Aquila. Possui uma ascensão reta de 19h 19m 53.04s e uma declinação de +11° 32′ 05.7″. Sua magnitude aparente é igual a 6.03. Considerando sua distância de 278 anos-luz em relação à Terra, sua magnitude absoluta é igual a 1.37. Pertence à classe espectral A2V. (pt)
  • 天鷹座ω2(Omega2 Aquilae),是從拉丁文的 ω2 Aquilae轉換而來,是拜耳命名法所賦予的名稱。這顆恆星是位在天球赤道上的星座,天鷹座的一顆恆星。它的視星等為6.0等,接近肉眼可以看見的下限。依據波特爾暗空分類法的尺度,這顆恆星要到天空足夠黑暗的荒郊野外才能用肉眼直接看到。當地球繞著太陽公轉時,這顆恆星的周年視差值為12.27mas,相當於與地球的有形距離為270光年(83秒差距),給出的誤差範圍在10光年。 分析這顆恆星的光譜,顯示的恆星光譜與A2V相匹配,表示它是A型主序星,大小是太陽的2倍。外大氣層的有效溫度為8,936K,使它輻射出A型星的白色色調。天鷹座ω2快速的投影轉速是每秒154公里。 (zh)
  • Omega2 Aquilae (ω2 Aql / 29 Aquilae)​ es una estrella en la constelación de Aquila.De magnitud aparente +6,02, comparte de la denominación de Bayer «Omega» con , si bien no existe relación física entre ambas estrellas.De acuerdo a la nueva reducción de los datos de paralaje de Hipparcos, Omega2 Aquilae se encuentra a 266 años luz del Sistema Solar. Omega2 Aquilae posee una masa de 2,1 masas solares y ha vivido el 60% de su vida como estrella de la secuencia principal.​ (es)
