克卜勒-160

克卜勒-160是星座天琴座中的主序帶恆星，大約在離開銀河臂的寬處。由美國國家航空暨太空總署領導的克卜勒任務首先詳細研究，發現他有顆類地行星。這顆恆星在質量和半徑上與太陽非常相似，有三顆已確認的行星和一顆未經證實的行星圍繞它運行。 克卜勒-160恆星相當古老，沒有可探測到的星周盤。這顆恆星的金屬量是未知的，據報導的值相互衝突，是太陽金屬量的40%或160%。 在這個系統（以及所有其他系統）中，搜索外星智慧的突破聆聽沒有發現潛在的技術簽名（英语：Technosignature）。 克卜勒-160系統中的兩顆行星候選者於2010年被發現，於2011年初發表，並在2014年確認。儘管它們的軌道週期比接近1：3，但行星克卜勒-160b和克卜勒-160c沒有軌道共振。 2020年發現了位於適居帶的另一塊岩石凌日行星候選者KOI-456.04，由於凌日時間變化解中的殘差，懷疑有更多的非凌日行星。據研究人員所知，KOI-456.04看起來不到地球大小的兩倍，而且繞克卜勒-160運行的距離，顯然與地球到太陽的距離大致相同（一個完整的軌道是378天）。也許最重要的是，它接收的光量大約是地球從太陽獲得的93%。非凌日行星候選者克卜勒-160d的質量在1到100個地球質量之間，軌道週期在大約7到50天之間。 2014年發現的系外行星列表 2020年發現的系外行星列表 克卜勒太空望遠鏡 Kepler-160 -- Rotationally variable Star.
