14 Andromedae is an orange giant star approximately 250 light-years away in the constellation of Andromeda. The star is a suspected variable star. It is thought that 14 Andromedae was formerly a white or a yellow-white dwarf star early in its life. As of 2008, an extrasolar planet is thought to be orbiting the star, being one of the few known planets to be orbiting an evolved intermediate-mass star.

Planetary system

In 2008, a planet (designated 14 Andromedae b) was announced to be orbiting the star. The planet was found to have a minimum mass of 4.8 Jupiter masses and orbiting in a circular orbit that takes 186 days to complete. The planet is one of the innermost planets around an evolved intermediate-mass star (such planets have only been discovered in clump giants).
