Alpha Herculis A is an asymptotic giant branch (AGB) star, a luminous red giant that has both hydrogen and helium shells around Beta Herculis is actually a binary system. The star can be seen with the naked eye, that is, you don't need a telescope/binoculars to see it. The figure of 161.53 that I have given is based on the value in the Simbad Hipparcos Extended Catalogue at the University of Strasbourg from 2012. A note about the calculations, when I'm talking about years, I'm talking non-leap years only (365 days). Sigma Herculis is a main star of the constellation outline. In this area there is one meteor shower that naturally occurs named, Tau Herculids. It is 380 light-years from Earth. USS Rutilicus (AK-113) was a United States Navy Crater class cargo ship named after the star. It can be found between the constellation of Lyra and the distinctive "Northern Crown".

It lies in the constellation Hercules and is of about third magnitude, its brightness varying by about a magnitude every 128 days. Mu Herculis is 27.4 light-years from Earth. [1], Although Beta Herculis appears to the naked eye to be a single star, in July 1899 the American astronomer W. W. Campbell discovered from spectroscopic measurements that its radial velocity varies, and concluded that it has a companion. There's no register feature and no need to give an email address if you don't need to. The 99 Herculis stars could be seen from Sol, 51 light-years distant, in the constellation of Hercules. Some constellations, exemplified by Orion, stand out brilliantly among their neighbors.But brightness does not necessarily mean unimportance, as testified by Hercules, one of the oldest and best known constellations in the sky even though its brightest star, Kornephoros, is third magnitude (albeit at the bright end of third, 2.77). Its mass is 4.66 Jupiters, it takes 4.9 years to complete one orbit of its star, and is 2.93 AU from its star. Its traditional name of Rasalgethi is derived from an Arabic phrase meaning, ‘the head of the Kneeler’. [4123] … Its discovery was announced in 2002. It has a diameter of roughly 400 solar diameters. The period of the system is around 410 days. Our own Sun is the brightest star and therefore has the lowest of all magnitudes, -26.74. Zeta Herculis A(a?)

Beta Herculis a une magnitude apparente de +2,8 et est de type spectral G7III. beta Herculis: Kornephoros: magn. In 2007, Hipparcos data was revised with a new parallax of 23.44000 which put Kornephoros at a distance of 139.15 light years or 42.66 parsecs. [21] Though, according to a 1971 NASA catalog, al-Nasaq al-Sha'āmī or Nasak Shamiya was the title for three other stars: Beta Serpentis as Nasak Shamiya I, Gamma Serpentis as Nasak Shamiya II and Gamma Herculis as Nasak Shamiya III. 99 Herculis is a star system located in the galaxy's Alpha Quadrant, a trinary star consisting of two F type stellar bodies associated with a third K type star. [18] The secondary star has a mass only 90% that of the Sun.[3]. Alpha designation for the constellation belongs to Ras Algethi which is situated at the bottom of the picture, just inside the Hercules boundary.
