OGLE-2016-BLG-1195Lb是一顆距離地球約1.3萬光年的太陽系外行星,母恆星為OGLE-2016-BLG-1195L[4][5]。該行星於2017年由韓國天文研究院所屬韓國微重力透鏡望遠鏡網朝鲜语외계행성_탐색시스템(Korean Microlensing Telescope Network,KMTNet)與史匹哲太空望遠鏡微引力透镜方式發現[3]。OGLE-2016-BLG-1195Lb的質量與地球近似,並且與母恆星的距離與日地距離相當。然而,它的母恆星的質量可能極低[4],甚至可能其實是棕矮星超低溫矮星亞恆星[6]。基於目前的觀測資料,OGLE-2016-BLG-1195Lb可能是極低溫的類地行星 [4]

部分天文學家以《星際大戰》系列電影中環境類似的虛構行星霍斯稱呼OGLE-2016-BLG-1195Lb[6]。更早之前美国国家航空航天局也將另一顆環境類似的系外行星OGLE-2005-BLG-390Lb與霍斯相比較[7]
