Fifteen stars in Hercules are known to be orbited by extrasolar planets.

14 Herculis has two planets. The planet 14 Herculis b had the longest period (4.9 years) and widest orbit (2.8 AU) at the time of discovery. The planet 14 Herculis corbits much further out with very low eccentricity.HD 149026 has a transiting hot Jupiter planet and is one of the most prominent and studied.HD 154345 has the planet HD 154345 b, a long period (9.095 years) and wide orbit (4.18 AU).HD 164922 has the first long period Saturn-like planet discovered. The mass is 0.36 MJ and semimajor axis of 2.11 AU.HD 147506 has the most massive transiting planet HAT-P-2b at the time of discovery. The mass is 8.65 MJ.HD 155358 has two planets around the lowest metallicity planet-harboring star (21% Sun). Both planets orbit in mild eccentricities.GSC 03089-00929 has a short transiting planet TrES-3. The period was 31 hours and undergoing orbital decay.Gliese 649 has a saturnian planet around the red dwarf star.HD 156668 has a 4.15 Earth mass plan
