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[2],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[1],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[3],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[8],使它輻射出A型星的白色色調</ref>[10]。天鷹座ω2快速的投影轉速是每秒154公里[9]。
