Pollux b, also cataloged as Beta Geminorum b (β Gem b / β Geminorum b) and or HD 62509 b, is an extrasolar planet approximately 34 light-years away in the constellation of Gemini (the Twins). This planet was discovered orbiting the star Pollux in 2006. The planet has a comparable mass to the gas giants in our solar system. It moves around Pollux in 1.61 years at a distance of 1.64 AU in a nearly circular orbit. This planet was originally suspected in 1993, and it wasn't published until June 16, 2006.
