'''HD 125612 c''' is an extrasolar planet which orbits the G-type [[Astronomy:Main sequence|main sequence]] [[Astronomy:Star|star]] [[Astronomy:HD 125612|HD 125612]], located approximately 188 [[Light year|light year]]s away in the [[Astronomy:Constellation|constellation]] [[Astronomy:Virgo (constellation)|Virgo]].<ref name="Lo Curto2010"/> The discovery of this planet was announced by the HARPS team on October 19, 2009, together with 31 other planets, including [[Astronomy:HD 125612 d|HD 125612 d]].<ref name="eso0939"/>

In April 2010, the [[Astronomy:Spitzer Space Telescope|Spitzer Space Telescope]] was used to search for the [[Astronomy:Transit|transit]] of this planet across the face of its host star. The initial light curve was consistent with a transit, however new observations with Spitzer in September 2010 did not confirm the transit signal. Analysis of both Spitzer light curves showed that the possibility of a transit was only 0.24% compared to 9.7% prior to these observations.<ref name="Gillon2017"/>
