The star HD164669 near the primary may be an optical double. 100 Herculis is a double star easily divisible in small amateur telescopes. Both components are magnitude 5.8 blue-white stars; they are 165 and 230 light-years from Earth. [10] There are several dimmer variable stars in Hercules.
Messier 13, or M13 (also designated NGC 6205 and sometimes called the Great Globular Cluster in Hercules, the Hercules Globular Cluster, or the Great Hercules Cluster), is a globular cluster of several hundred thousand stars in the constellation of Hercules.

B's two components are a primary yellow giant star and a secondary, yellow-white dwarf star in a 51.578 day orbit. [20] Alpha Herculis A is an asymptotic giant branch (AGB) star, a luminous red giant that has both hydrogen and helium shells around a degenerate carbon-oxygen core. It is the second nearest AGB star to the Sun.
Beta Herculis (β Herculis, abbreviated Beta Her, β Her), formally named Kornephoros / k ɔːr ˈ n ɛ f ə r ə s /, [16] or Rutilicus, is a binary star and the brightest star in the northern constellation of Hercules [3] at a base apparent visual magnitude of 2.81. This is a suspected variable star with an apparent magnitude that may rise as ...
Xi Herculis is a solitary [11] star located within the northern constellation of Hercules. The star is visible to the naked eye with an apparent visual magnitude of 3.70. [ 2 ] Based upon an annual parallax shift of 23.85 mas as seen from Earth, it is located 137 light years from the Sun . [ 1 ]
HD 164595 is a wide binary star [12] system in the northern constellation of Hercules. [1] The primary component of this pair hosts an orbiting exoplanet.The system is located at a distance of 92 light years from the Sun based on parallax measurements, [2] and is drifting further away with a radial velocity of 2.0 km/s. [6]
14 Herculis or 14 Her is a K-type main-sequence star 58.4 light-years (17.9 parsecs) away in the constellation Hercules. It is also known as HD 145675. Because of its apparent magnitude, of 6.61 the star can be very faintly seen with the naked eye. As of 2021, 14 Herculis is known to host two exoplanets in orbit around the star. [4]
