81 Ceti b is an extrasolar planet approximately 317 light years away in the constellation of Cetus. This planet is classified as Super-Jupiter because it has minimum mass 5.3 times that of Jupiter and the speculated radius 0.932 times. This planet orbits at the average distance of 2.5 AU, taking about 2.6 years to revolve with 20.6% eccentricity. In Sudarsky scheme, this planet is classified as with speculated temperature of 527 K. This planet was discovered on July 3, 2008 by Sato "et al", who used Doppler Spectroscopy and found the wobbling of the star caused by the planet’s gravity during its revolution.
