The stars orbit each other over a period of 34.45 years, with a semi-major axis of 1.33" and an eccentricity of 0.46. This star is radiating more than six times the luminosity of the Sun at an effective temperature of 5,820 K. The secondary component (Component B) is about the same size and mass as the Sun, with an effective temperature of 5,300 K. Both stars are rotating slowly. Both stars have severely low abundances of beryllium. Luminosity is the amount of energy that a star pumps out and its relative to the amount that our star, the Sun gives out. Colour and Temperature Based on the star's spectral type of G8III, Kornephoros's colour and type is yellow giant star. Density, temperature, and pressure all increase at the center; but the outer envelope responds to changes in the core by expanding. The Zeta Reticuli system belongs to the Zeta Herculis Moving Group of stars that share a common motion through space, suggesting that they have a common origin. The figure is derived at by using the formula from SDSS rather than peer reviewed papers. 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 What is Catherine Zeta-Jones favorite color? The surface area increases as the surface temperature decreases, yielding a constant luminosity. Parallax measurements put it at a distance of about 35.0 light-years (10.7 parsecs) from Earth. Proper Motion details the movements of these stars and are measured in milliarcseconds. Parallax measurements put it at a distance of about 35.0 light-years (10.7 parsecs) from Earth. The number of A.U. [1], The primary member is a subgiant star that is somewhat larger than the Sun and has just begun to evolve away from the main sequence as the supply of hydrogen at its core becomes exhausted. Rutilicus is a Subgiant Star type star. [9], The orbit and other information about the A-B binary is documented within the Washington Double Star Catalog. The pair is believed to be part of the "Zeta Herculis" stellar moving (kinematic) group of high velocity stars (which no longer includes Zeta Herculis). The Galacto-Centric Distance is the distance from the star to the Centre of the Galaxy which is Sagittarius A*. [3] It has about 2.6 times the radius of the Sun and 1.45 times the Sun's mass. ζ Herculis (zeta Herculis) ζ Herculis is a variable and double hypergiant star in the constellation of Hercules. [10] Two astrometric studies have failed to detect a third component to the A-B binary. With a stellar classification G7.5IIIb, it is yet considerably larger having a mass that is 2.3 times solar and a radius 9.8 times. Go anywhere, anytime with tires built to dominate off-road and deliver efficiency on them. The star can be seen with the naked eye, that is, you don't need a telescope/binoculars to see it. In 2007, Hipparcos data was revised with a new parallax of 93.32000 which put Rutilicus at a distance of 34.95 light years or 10.72 parsecs. There exist radial-velocity observations of Zeta Herculis dating back to 1983. alpha her, eta her, pi her, zeta her, epsilon her. Rutilicus has an apparent magnitude of 2.81 which is how bright we see the star from Earth. System Summary. Distance: 328 a.l.. A mediaeval state roughly equivalent to modern Montenegro. A note about the calculations, when I'm talking about years, I'm talking non-leap years only (365 days). If you need the diameter of the star, you just need to multiple the radius by 2. This group includes: φ2 Pavonis, ζ Reticuli, 1 Hydrae, Gl 456, Gl 678, and Gl 9079. Using the 2007 distance, the star is roughly 2,211,143.32 Astronomical Units from the Earth/Sun give or take a few. This star system belongs to the Zeta Herculis Moving Group of stars that share a common motion through space, suggesting that they have a common origin.

The New Horizons space probe is the fastest probe that we've sent into space at the time of writing. It spins at 1.74 km/s. Now click on 95 Herculis on the map. distance from earth magnitude color and surface temperature The source of the information if it has a Hip I.D. Zeta (2) Reticuli is brighter than Zeta (1). Apparent Magnitude is also known as Visual Magnitude. It has a combined apparent visual magnitude of 2.81,[2] which is readily visible to the naked eye. The two stars have common proper motion and equal radial velocities, making them a permanent pair, not a chance co-location of stars. [6] This distance is large enough so that the two stars do not have a significant tidal effect on each other. ... It’s a Magnitude 7.4 and has a surface temperature of about 85,000 K. Its main component star is a subgiant with 2.6 times the Sun’s radius, 1.45 times its mass, and 6 times its luminosity, while its companion is a yellow dwarf not unlike our own sun. Mach 1 is the speed of sound, Mach 2 is twice the speed of sound. Rutilicus estimated radius has been calculated as being 2.82 times bigger than the Sun. 313, 873 Abs. It is also known as M13 and its brightest star is called V11 which is bright red in color. The empirical scale of temperatures of the low main sequence (F0V-K5V). With a surface temperature of 5,861 K, it has 97.2% of the Sun’s luminosity. [6] There may be a faint third member of this system, although little is known about it. The Right Ascension is how far expressed in time (hh:mm:ss) the star is along the celestial equator. Corncorde before it was retired was the fastest commercial airline across the Atlantic and only one that could do Mach 2. Based upon parallax measurements, this system is located at a distance of about Template:Convert from the Earth. You can decline to give a name which if that is the case, the comment will be attributed to a random star. [10][7], This system forms part of the Zeta Herculis moving group of stars. Exoplanets. The star's Galacto-Centric Distance is 7,395.00 Parsecs or 24,119.78 Light Years. U.G. Rutilicus is a Binary or Multiple star system. zeta Herculis is another double star composed of a subgiant and a faint companion star. Its nothing to fear as the stars are so far apart, they won't collide in our life-time, if ever. [6] Though it only shines with an apparent magnitude of 3.48, it is part of the "Keystone" asterism , visible overhead in the mid-summer night sky to northern observers, allowing it to be easily recognized. (See Sloan Digital Sky Survey. It is purely that the distance was recalculated. [ 3 ] The magnitude difference between the A-B pair is 1.52 ± 0.04 magnitudes (at 700 nm). All messages will be reviewed before being displayed. The primary component in the system is a subgiant star belonging to the spectral class F9 IV, which is orbited by a smaller companion star at a separation of 1.5 arc seconds, with a period of 34.45 years. has done some calculations as to how long it will take going at differing speeds. A name is preferred even if its a random made up one by yourself. This star system belongs to the Zeta Herculis Moving Group of stars that share a common motion through space, suggesting that they have a common origin. Magnitude, whether it be apparent/visual or absolute magnitude is measured by a number, the smaller the number, the brighter the Star is.
