HD 208487 c is an extrasolar planet located approximately 144 light-years away in the constellation of Grus, orbiting the star HD 208487. It has mass similar to HD 208487 b, but it orbits 3.6 times farther than HD 208487 b. This planet was first discovered on November 17, 2005 and confirmed on August 17, 2006, and then published on December 6, 2006. It was discovered by Gregory "et al" from using Bayesian Kepler Periodogram in Monte-Carlo Observatory.
