Zeta Herculis is a binary star system in the constellation Hercules.
It has a class of G0V which means it is similar to our Sun but is moving away from the main sequence.
It's companion star is a class K0V
Sadatoni, also known as Zeta Aurigae, is a binary star . So, one star is a bright giant or a supergiant. It's companion is a main-sequence star.
Beta and Alpha Herculis are both 2nd Magnitude (2.78) stars
The apparent visual magnitude of Beta Herculis is 2.81. It has been known since 1899 that it is in fact a binary star, and modern measurements (including satellite telescope) have resolved the motions and apparent sizes of the two bodies.
Zeta is a number - it is not the whole star name. Each constellation has a Zeta. What's the rest of the star name (it will look very similar to the constellation name but probably ends with the letter "i")?
Zeta Draconis is a binary star system where one of the stars, Zeta Draconis A, has a luminosity around 14 times that of the sun.
red star
It is a G-type giant star.
Zeta Herculis (Rutilicus) is a binary star system in the constellation Hercules.It is the second brightest star in the constellation with an apparent magnitude of +2.89
Delta Herculis (Sarin) is a star in the constellation Hercules.It is a type A3V star and will have a temperature of between7,500oK and 10,000oK
The main stars in the Hercules constellation include Alpha Herculis (Rasalgethi), Beta Herculis (Kornephoros), Delta Herculis (Sarin), and Zeta Herculis (Heze). These stars are among the brightest in the constellation and help in forming the shape associated with the mythical hero Hercules.
Zeta Phe is a blue-white main sequence star that is approximately 610 light-years away from Earth. It is a subgiant star with a spectral type of B7 IV.
Beta Herculis is actually a binary system. The main star, of the two, is yellow.
Zeta Draconis (Aldhibah or Nodus I) is a type B8 star, which means it has a colour of blue-white and a temperature of 10,000--30,000 K
Zeta Pegasi is a star in the constellation Pegasus. It has a spectral class of B8 which means it's temperature is10,000 - 30,000 K and will have a colour of blue to blue-white.
Hercules is large, but it doesn't contain any really bright stars. (The globular cluster called M13 is of interest.) These are the brightest stars (apparent magnitude) in Hercules: Kornephoros, Zeta Herculis, Sarin, Pi Herculis, Rasalgethi.
It is called Herculis
This star is also known as Beta Herculis, so it is obviously in constellation Hercules.
