HD 125612 c is anextrasolar planet which orbits theG-typemain sequencestarHD 125612, located approximately 188light years away in theconstellationVirgo.[2] The discovery of this planet was announced by theHARPS team on October 19, 2009, together with 31 other planets, includingHD 125612 d.[3]

In April 2010, theSpitzer Space Telescope was used to search for thetransit 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]
