'''HD 102117b'''是一颗位于[[半人马座]]、距离地球约137光年的系外行星，其母星为[[HD 102117]]。该行星是一颗小型[[类木行星]]，其大小仅为木星的1/5。其轨道十分接近其母星，但还未如著名的[[飞马座51b]]一般进入“烈焰轨道”(torch orbit)。该行星是迄今为止发现的最小的系外行星之一。<ref>{{cite journal | url=http://www.iop.org/EJ/article/0004-637X/646/1/505/64046.html | author=Butler ''et al.'' | title=Catalog of Nearby Exoplanets | journal=The [[Astrophysical Journal]] | volume=646 | issue=1 | pages=505–522 | year=2006 | doi=10.1086/504701 | access-date=2009-07-12 | archive-date=2009-05-02 | archive-url=https://www.webcitation.org/5gTrfcenD?url=http://www.iop.org/EJ/article/0004-637X/646/1/505/64046.html | dead-url=no }}</ref><br />
