HD 99109 b is an extrasolar planet approximately 197 light-years away in the constellation of Leo. The planet was confirmed in 2006 to be orbiting the orange dwarf star HD 99109. The planet is about one half the mass of Jupiter, classifying the planet as a Jovian planet. Because of its distance and suspected temperature, the planet is thought to be orbiting within the habitable zone of its parent star (presumably in the central region). The orbital eccentricity is about the same as planet Mars.
