It has a minimum mass of 2.7 times that of Jupiter and an orbital period of 184 days (corresponding to semi-major axis of 0.81 AU). It was discovered and announced by Sato on February 19, 2008. A gas giant (sometimes also known as a Jovian planet after the planet Jupiter, or giant planet) is a large planet that is not primarily composed of rock or other solid matter. There are four gas giants in the Solar System: Jupiter, Saturn, Uranus, and Neptune. Many extrasolar gas giants have been identified orbiting other stars.
