Constellation in the northern celestial hemisphere
The solar apex is the direction of the Sun's motion with respect to the Local Standard of Rest. This is located within the constellation of Hercules, around coordinates right ascension and declination The north pole of the supergalactic coordinate system is located within this constellation at right ascension and declination .

Hercules has no first or second magnitude stars. However, it does have several stars above magnitude 4. Alpha Herculis, traditionally called Rasalgethi, is a triple star system, partly resolvable in small amateur telescopes, 359 light years from Earth. Its common name means "the kneeler's head". The primary is an irregular variable star; it is a bright giant with a minimum magnitude of 4 and a maximum magnitude of 3. It has a diameter of roughly 400 solar diameters. The secondary, a spectroscopic binary that orbits the primary every 3600 years, is a blue green hued star of magnitude 5.6. Beta Herculis, also called Kornephoros, is the brightest star in Hercules. It is a yellow giant of magnitude 2.8, 148 light years from Earth; kornephoros means club bearer. Delta Herculis A is a double star divisible in small amateur telescopes. The primary is a blue white star of magnitude 3.1, and is 78 light years from Earth. The optical companion is of magnitude 8.2. Gamma Herculis is also a double star divisible in small amateur telescopes. The primary is a white giant of magnitude 3.8, 195 light years from Earth. The optical companion, widely separated, is 10th magnitude. Zeta Herculis is a binary star that is becoming divisible in medium aperture amateur telescopes, as the components widen to their peak in 2025. The system, 35 light years from Earth, has a period of 34.5 years. The primary is a yellow tinged star of magnitude 2.9 and the secondary is an orange star of magnitude 5.7. Hercules hosts further quite bright double stars and binary stars. Kappa Herculis is a double star divisible in small amateur telescopes. The primary is a yellow giant of magnitude 5.0, 388 light years from Earth; the secondary is an orange giant of magnitude 6.3, 470 light years from Earth. Rho Herculis is a binary star 402 light years from Earth, divisible in small amateur telescopes. Both components are blue green giant stars; the primary is magnitude 4.5 and the secondary is magnitude 5.5. 95 Herculis is a binary star divisible in small telescopes, 470 light years from Earth. The primary is a silvery giant of magnitude 4.9, and the secondary is an old, reddish giant star of magnitude 5.2. 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. between his more outstretched foot (Omicron Herculis) and Vega (in neighboring Lyra).

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 c orbits much further out with very low eccentricity. It was discovered in 2005 but was only confirmed in 2021. HD 149026 has a transiting hot Jupiter planet. 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. More planets have been discovered since. 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 3b. The period was 31 hours. Gliese 649 has a saturnian planet around the red dwarf star. HD 156668 has an Earth mass planet with a minimum mass of four Earth masses. HD 164595 is a G type star with one known planet, HD 164595 b.
TOI 561 has four, or possibly five planets. The innermost of which, TOI 561 b, is notable because it is an ultra short period planet.

Hercules contains two bright globular clusters: M13, the brightest globular cluster in the northern hemisphere, and M92. It also contains the nearly spherical planetary nebula Abell 39. M13 lies between the stars η Her and ζ Her; it is dim, but may be detected by the unaided eye on a very clear night. M13, visible to both the naked eye and binoculars, is a globular cluster of the 6th magnitude that contains more than 300,000 stars and is 25,200 light years from Earth. It is also very large, with an apparent diameter of over 0.25 degrees, half the size of the full moon; its physical diameter is more than 100 light years. Individual stars in M13 are resolvable in a small amateur telescope. M92 is visible as a fuzzy star in binoculars, like M13; it is denser and smaller than the more celebrated cluster. The oldest globular cluster known at 14 billion years, its stars are resolvable in a medium aperture amateur telescope. NGC 6210 is a planetary nebula of the 9th magnitude, 4000 light years from Earth visible as a blue green elliptical disk in amateur telescopes larger than 75 mm in aperture. As of 22 June 2018, this astronomical event has generated a very large amount of interest among astronomers throughout the world and may be, as of 22 June 2018, considered a supernova tentatively named Supernova 2018cow. The Hercules Cluster (Abell 2151) is a cluster of galaxies in Hercules. The brightest radio source in the constellation is Hercules A, an elliptical galaxy located 2.1 billion light years away with a supermassive black hole with a mass of 2.5 billion solar mass that has radio jets that extend for one and a half million light years. Another bright radio source in Hercules is the quasar 3C 345 which has a jet that appears to move faster than the speed of light. The Hercules–Corona Borealis Great Wall, the largest structure in the universe, is in Hercules.

The traditional visualization imagines α Herculis as Hercules's head; its name, Rasalgethi, literally means "head of the kneeling one". Hercules's left hand then points toward Lyra from his shoulder (δ Herculis), and β Herculis, or Kornephoros ("club bearer") forms his other shoulder. His narrow waist is formed by ε Herculis and ζ Herculis. Finally, his left leg (with θ Herculis as the knee and ι Herculis the foot) is stepping on Draco's head, the dragon/snake who Hercules has vanquished and perpetually gloats over for eternities.

A common form found in modern star charts uses the quadrangle formed by π Her, η Her, ζ Her and ε Her (known as the "Keystone" asterism) as Hercules's torso.

H. A. Rey has suggested an alternative visualization in which the "Keystone" becomes Hercules's head. This quadrangle lies between two very bright stars: Vega in the constellation Lyra and α CrB (Alphecca) in the constellation Corona Borealis. The hero's right leg contains two bright stars of the third magnitude: α Her (Rasalgethi) and δ Her (Sarin). The latter is the right knee. The hero's left leg contains dimmer stars of the fourth magnitude which do not have Bayer designations but which do have Flamsteed numbers. The star β Her belongs to the hero's outstretched right hand, and is also called Kornephoros.
