HD 108874 b is a gas giant announced in 2003. The orbit lies in the star's habitable zone.[1] It is expected that any moons orbiting this planet are enriched in carbon, and are thus quite different from the silicate-rich bodies in the Solar System.[2] The planet is possibly in a 4 : 1 orbital resonance with HD 108874 c.
The jovian planet HD 108874 b was discovered by the US-based team led by Paul Butler, Geoffrey Marcy, Steven Vogt, and Debra Fischer. A total of 20 radial velocity observations, obtained at the W. M. Keck Observatory in Hawaii between 1999 and 2002, were used to make the discovery.
