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 a eccentricity of 20.6.[1]

Discovery

The preprint announcing this planet was submitted to the arXiv electronic repository on July 2, 2008 by Bun'ei Sato and collaborators, who discovered it using the Doppler Spectroscopy method, during the Okayama Planet Search radial velocity survey of G and K giants at Okayama Astrophysical Observatory.[1]
