'''GJ 758 C'''是一颗环绕[[黄矮星|GV恒星]][[GJ 758]]运行的类行星天体，可能是一颗[[太阳系外行星]]，也有可能是[[褐矮星]]。它位于[[天琴座]]，距离地球约54.5[[光年]]。<br />
<br />
GJ 758 B是由[[日本]][[昴星团望远镜]]的高对比度日冕成像仪和自适应光学系统(HiCIAO)通过遮挡中央恒星的光芒而直接发现的。如果观测结果得到确认GJ 758 B将是少数几颗通过直接探测而发现的[[太阳系外行星]]<ref>{{Cite web |url=http://www.centauri-dreams.org/?p=10517 |title=Possible Planet Around a G-class Star |accessdate=2010-02-19 |archive-date=2016-01-29 |archive-url=https://web.archive.org/web/20160129212024/http://www.centauri-dreams.org/?p=10517 |dead-url=no }}</ref>。<br />
