Pollux has one confirmed extrasoloar planet in orbit.  The planet, unofficially called "Polydeuces" was first detected in 1993, but was not confirmed until June 16, 2006.  Polydeuces is a [[Jupiter]] class [[gas giant]] with a minimum mass of 2.3 times of Jupiter.  The planet orbits Pollux with an average distance of 1.64 AU and takes around 1.6 years to complete.<ref>http://lanl.arxiv.org/abs/astro-ph/0606517</ref>

For an [[terrestrial planet|Earth-like]] world to have liquid [[water]] on its surface, it would need to be centered around 5.7 Au from Pollux, equivalent to Jupiter's orbit of the Sun.
