Gliese 667 Cc
Gliese 667 Cc was first found by the European Southern Observatory on 21 November 2011. They used the wobble method (also known as radial velocity). They watched how the star "wobbled" as Gliese 667 Cc circled around its star. On 2 February 2012 researchers at the University of Göttingen and the Carnegie Institution for Science confirmed the planet's existence.
