14 Andromedae b Wikipedia
14 Andromedae b (abbreviated 14 And b), also named Spe, 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.
In July 2014 the International Astronomical Union launched a process for giving proper names to certain exoplanets and their host stars. The process involved public nomination and voting for the new names. In December 2015, the IAU announced the name Spe for this planet. The winning name was based on that submitted by the Thunder Bay Centre of the Royal Astronomical Society of Canada); namely 'Spes', Latin for 'hope'. (Spes was also the Roman goddess of hope.) The IAU substituted the ablative form 'Spe', which means 'where there is hope', to match that given to the host star at the same time.
