6. HD 131399 Ab: HD 131399 Ab曾被認定是一顆環繞三合星系統HD 131399中的成員恆星HD 131399 A的太陽系外行星，推測其距離地球約320光年，天球上位於半人馬座。最初將其視為行星時，認為它與該三合星系統的另外兩顆恆星相互環繞，並且一起環繞著恆星HD 131399 A運行。然而2017年至2022年逐步證實HD 131399 Ab應為背景恆星而非行星，因此並非在該三合星系統之下運行，其光譜近似橙矮星或紅矮星，由於擁有異常高的自行運動（位於移動速度最快的前4%恆星中）而造成觀測上的誤解。 HD 131399 Ab的年齡約1600萬年，質量大約是4 ± 1 MJ，表面溫度大約是850 K（577 °C）（± 50 K），因此它是至今直接影像法發現的系外行星中溫度與質量最低的系外行星之一。該行星.
