14 Andromedae b
14 Andromeda b or 14 And b is an extrasolar planet approximately 249 light years away in the constellation of Andromeda. The 186-day period planet orbits about 83% the Earth-Sun distance from the giant star 14 Andromedae. It has a minimum mass 4.8 times the mass of Jupiter. The planet orbits with an eccentricity of 0.0094, which means the orbital distance over the course of its revolution varies by only 0.02 AU. This planet was discovered on July 3, 2008 by Sato ''et al.'', who discovered the wobbling of 14 Andromedae caused by the planet’s gravity during its orbit with the Doppler spectroscopy.〔
The planet and its host star is one of the planetary systems selected by the International Astronomical Union as part of their public process for giving proper names to exoplanets and their host star (where no proper name already exists).〔(NameExoWorlds: An IAU Worldwide Contest to Name Exoplanets and their Host Stars ). IAU.org. 9 July 2014〕〔(NameExoWorlds ).〕 The process involves public nomination and voting for the new names, and the IAU plans to announce the new names in mid-November 2015.〔(NameExoWorlds ).〕
