94 Ceti b or 94 Ceti Ab to distinguish it from the distant red dwarf companion, is an extrasolar planet orbiting its star once every 1.2 years. It was discovered on August 7, 2000 by a team led by Michel Mayor.[2]

It is most stable if its inclination is about 65 or 115, yielding a mass of about 1.85 that of Jupiter.[1]
