HD 210702 b is an exoplanet located approximately 182 light-years away in the constellation of Pegasus, orbiting the star HD 210702. This planet, together with HD 175541 b and HD 192699 b, are planets around intermediate mass stars that were announced in April 2007 by Johnson et al. It has at least twice the mass of Jupiter and it orbits with semimajor axis of 1.17 AU, corresponding to a period of 341.1 days.
Planets around intermediate mass subgiants provide clues for the history of formation and migration of planets around A-type stars.
