81 Ceti b (abbreviated 81 Cet b) is an extrasolar planet approximately 300 light years away in the constellation of Cetus. It orbits the G-type giant star 81 Ceti at an average distance of 2.5 AU, taking about 2.6 years to revolve with 20.6% eccentricity.[1] 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.
