HD 102117 b is a planet that orbits the star HD 102117. The planet is a small gas giant a fifth the size of Jupiter. It orbits very close to its star, but not in a "torch orbit" like the famous 51 Pegasi b. It is one of the smallest extrasolar planets discovered so far.
In 2004, the Anglo-Australian Planet Search announced a planet orbiting the star HD 102117. A short time later the HARPS team also announced the presence of a planet around this same star HD 102117. Both groups detected this planet using the radial velocity method.
