HD 11964 c is an extrasolar planet approximately 110 light-years away in the constellation of Cetus. The planet was discovered in a close-orbit around the yellow subgiant star HD 11964. The planet has a minimum mass 35 times the mass of Earth and is located in a mildly eccentric orbit which takes almost 38 days to complete. HD 11964 c was a possible planet discovered on the same day as HD 11964 b in 2005. HD 11964 c was first proposed in a paper published in 2007,[1] and finally confirmed with new data presented in a review of multi-planet systems which appeared on the arXiv preprint website in 2008.
Some sources have used the designation "HD 11964 b" for this planet,[2] [3] however in their review of the properties of multi-planet extrasolar planetary systems, the discovery team has stated that the correct designation for this planet is HD 11964 c and the reversed system was due to confusion related to private communications between various groups of astronomers.
