With a surface temperature of 5,861 K, it has 97.2% of the Sun’s luminosity. [4126] pi Herculis, also known as Fudail ("excellent in character"), is an orange giant. The horizontal axis shows a variable related to surface temperature, such as the B-V color index, the spectral type, or the actual temperature. ζ Herculis (zeta Herculis) ζ Herculis is a variable and double hypergiant star in the constellation of Hercules. Both Zeta 1 and Zeta 2 Reticuli are slightly metal deficient, with only about 60% of the Sun’s metallicity. [6] This distance is large enough so that the two stars do not have a significant tidal effect on each other. do you know their: what type of star they are [super giant, main sequence, etc.] 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. Proper Motion details the movements of these stars and are measured in milliarcseconds. [11], Multiple star system in the constellation Hercules, "Statistics of spectroscopic sub-systems in visual multiple stars", Centre de données astronomiques de Strasbourg, https://en.wikipedia.org/w/index.php?title=Zeta_Herculis&oldid=918263450, Creative Commons Attribution-ShareAlike License, This page was last edited on 27 September 2019, at 20:25. Zeta Herculis (ζ Her, ζ Herculis) is a multiple star system in the constellation Hercules. For Rutilicus, the location is 16h 41m 17.48 and +31° 36` 06.8 . Density, temperature, and pressure all increase at the center; but the outer envelope responds to changes in the core by expanding. [10][7], This system forms part of the Zeta Herculis moving group of stars. 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. In the HR diagram, the star appears on … (See Sloan Digital Sky Survey. System Summary. All stars like planets orbit round a central spot, in the case of planets, its the central star such as the Sun. The Sun's radius is 695,800km, therefore the star's radius is an estimated 1,960,045.73.km. Hipparcos was a E.S.A. The star's effective temperature is 5,820 Kelvin which is hotter than our own Sun's effective Temperature which is 5,777 Kelvin. 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). Rutilicus is a Binary or Multiple star system. The value comes from the Hipparcos Extended Catalog. [3] It has about 2.6 times the radius of the Sun and 1.45 times the Sun's mass. w062: Temperature, Color, Bolometric-Correction Calibrations ---Astron. ... It’s a Magnitude 7.4 and has a surface temperature of about 85,000 K. All messages will be reviewed before being displayed. Rutilicus Facts. The map was generated using Night Vision, an awesome free application by Brian Simpson. Our own Sun is the brightest star and therefore has the lowest of all magnitudes, -26.74. Zeta (2) Reticuli is brighter than Zeta (1). Apparent Magnitude is also known as Visual Magnitude. Zeta Herculis is a multiple star with a combined apparent magnitude of 2.81, only 35 light years distant from Earth. – Zeta Herculis, the second brightest star in Hercules, is a multiple star system found 35 light years from our solar system with a visual magnitude of 2.81. There exist radial-velocity observations of Zeta Herculis dating back to 1983. [6] There may be a faint third member of this system, although little is known about it. The items in red are values that I've calculated so they could well be wrong. The Radial Velocity, that is the speed at which the star is moving away/towards the Sun is -67.80000 km/s with an error of about 0.20 km/s . A faint star will have a high number. Built for maximum durability and all-season, all-weather capabilities, Hercules SUV and Light Truck tires are rugged enough to dominate dirt like no other. 313, 873 Abs. 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. The star can be seen with the naked eye, that is, you don't need a telescope/binoculars to see it. satellite operation launched in 1989 for four years. Using the original Hipparcos data that was released in 1997, the parallax to the star was given as 92.63000 which gave the calculated distance to Rutilicus as 35.21 light years away from Earth or 10.80 parsecs. The star's effective temperature is 4,887 Kelvin which is cooler than our own Sun's effective Temperature which is 5,777 Kelvin A name is preferred even if its a random made up one by yourself. However with the 2007 release of updated Hipparcos files, the radius is now calculated at being round 2.79. It is the brightest of the four stars that form the Keystone asterism. WikiMatrix WikiMatrix . If the R.A. is positive then its eastwards. Rutilicus Iron Abundance is 0.02 with an error value of 9.99 Fe/H with the Sun has a value of 1 to put it into context. The visual binary Zeta Herculis (HR6212, HD150680) was discovered by Herschel in 1782, according to Lewis (1906). Distance: 328 a.l.. A mediaeval state roughly equivalent to modern Montenegro. 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. All files associated with The Constellations Web Page are Mach 1 is the speed of sound, Mach 2 is twice the speed of sound. Usually given as a "bright giant" (but sometimes as a supergiant), Pi Her radiates 1330 solar luminosities into space from its coolish 4110 Kelvin surface. Magnitude, whether it be apparent/visual or absolute magnitude is measured by a number, the smaller the number, the brighter the Star is. WikiSky.org.) Eta Herculis is a G-Type star. Delta Herculis (δ Herculis, abbreviated Delta Her, δ Her) is a multiple star system in the constellation of Hercules.Though it only shines with an apparent magnitude of 3.12, it is the third-brightest star in its constellation.

Rutilicus has an apparent magnitude of 2.81 which is how bright we see the star from Earth. zeta Herculis is another double star composed of a subgiant and a faint companion star. An Astronomical Unit is the distance between Earth and the Sun. It spins at 1.74 km/s. The number of A.U. [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. Some believe that they are focused on enslaving the world’s population, though it is unclear why. The New Horizons space probe is the fastest probe that we've sent into space at the time of writing. From the southern hemisphere the pair can be seen as a naked eye double star in very dark skies. Colour and Temperature Based on the star's spectral type of G8III, Kornephoros's colour and type is yellow giant star. The color of a star reflects the temperature of its surface, from tepid red-hot (far right) to If you need the diameter of the star, you just need to multiple the radius by 2. Parallax measurements put it at a distance of about 35.0 light-years (10.7 parsecs) from Earth. The source of the information if it has a Hip I.D. The diagram is the usual base for the classification of stars and is used to describe their evolution. Using the most recent figures given by the 2007 Hipparcos data, the star is 34.95 light years away from us. Rutilicus estimated radius has been calculated as being 2.82 times bigger than the Sun. Note: the temperature increases from right to left. Both stars are solar analogs that share similar characteristics with the Sun. The empirical scale of temperatures of the low main sequence (F0V-K5V). Information regarding Metallicity and/or Mass is from the E.U. In the galactic coordinate system , the [U, V, W] components of the space velocity for this system are equal to [−70.2, −47.4, +16.4] km/s for ζ 1 and [−69.7, −46.4, +16.8] km/s for ζ 2 . distance from earth magnitude color and surface temperature [10] Two astrometric studies have failed to detect a third component to the A-B binary. is from Simbad, the Hipparcos data library based at the University at Strasbourg, France. When the value is negative then the star and the Sun are getting closer to one another, likewise, a positive number means that two stars are moving away. This group includes: φ2 Pavonis, ζ Reticuli, 1 Hydrae, Gl 456, Gl 678, and Gl 9079. It has a combined apparent visual magnitude of 2.81,[2] which is readily visible to the naked eye. alpha her, eta her, pi her, zeta her, epsilon her.
