TRAPPIST-1
TRAPPIST-1，又嗌 2MASS J23062928-0502285[1]，係粒超低溫紅矮星[2]，離開地球 39.13光年（12.0秒差距），喺水瓶座。
馬西矯倫（Michaël Gillon）為首嘅天文研究小組，屬於比利時列日大學天文物理與地球物理研究所[3]，用喺智利喇莎娜天文台嘅 TRAPPIST (Transiting Planets and Planetesimals Small Telescope) 望遠鏡，以 transit photometry，發現三個地球大細嘅行星。最裏頭嘅兩粒星係喺宜居帶裏面，或者啱啱喺外面[4][5]。研究小組喺2016年5月號 Nature 雜誌嘅發表；2015年9月至12月嘅觀察嘅研究結果[6]。
2017年2月22號，天文學家宣布圍繞 TRAPPIST-1 嘅外行星加多四個。 而令圍繞星球運行嘅行星總數有七個，其中至少兩個，亦可能全部，喺宜居帶[7][8]。
