81 Ceti b

81 Ceti b (abbreviated 81 Cet b) is an extrasolar planet approximately 331 light years away in the constellation of Cetus. It is estimated to be 5.3 times the mass of Jupiter which also makes it a gas giant [3] [4]. 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 an eccentricity of 20.6.[5]

    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.[5]

    gollark: Look, you may never know my *real* motivations.
    gollark: Retroactively.
    gollark: This is why I orchestrated the campaign to dethrone you.
