HD 125612 c is an extrasolar planet which orbits the G-type main sequence star HD 125612, located approximately 188 light years away in the constellation Virgo.[2] The discovery of this planet was announced by the HARPS team on October 19, 2009, together with 31 other planets, including HD 125612 d.[3]

In April 2010, the Spitzer Space Telescope was used to search for the 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.[4]
