Its nothing to fear as the stars are so far apart, they won't collide in our life-time, if ever. You can decline to give a name which if that is the case, the comment will be attributed to a random star. ; Based on the spectral type (F9IV) of the star, the star's colour is yellow to white . It is orbited by a smaller companion star at a mean angular separation of 1.5 arcseconds, which corresponds to a physical separation of about 15 Astronomical Units. Some believe that they are focused on enslaving the world’s population, though it is unclear why. The items in red are values that I've calculated so they could well be wrong. From the southern hemisphere the pair can be seen as a naked eye double star in very dark skies. Using the most recent figures given by the 2007 Hipparcos data, the star is 34.95 light years away from us. ... It’s a Magnitude 7.4 and has a surface temperature of about 85,000 K. Based on the star's spectral type of F9IV , Rutilicus's colour and type is yellow to white subgiant star. The map was generated using Night Vision, an awesome free application by Brian Simpson. The constellations that we see today will be different than they were 50,000 years ago or 50,000 years from now. Both stars have severely low abundances of beryllium. ζ Herculis (zeta Herculis) ζ Herculis is a variable and double hypergiant star in the constellation of Hercules. Zeta Herculis A is a yellowish star that is brighter, more massive, and further evolved than our Sun, Sol, while its stellar companion B is dimmer, cooler, and. Thanks to its high brightness, ζ Herculis is clearly visible when observed from locations with dark skyes, and should be … The time it will take to travel to this star is dependent on how fast you are going. 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. Density, temperature, and pressure all increase at the center; but the outer envelope responds to changes in the core by expanding. A faint star will have a high number. WikiSky.org.) 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. 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. Our own Sun is the brightest star and therefore has the lowest of all magnitudes, -26.74. [3] It has about 2.6 times the radius of the Sun and 1.45 times the Sun's mass. Zeta (2) Reticuli is brighter than Zeta (1). Zeta 2 Reticuli is slightly larger and more massive, with a size of 0.99 solar radii and a mass of 0.985 solar masses. is from Simbad, the Hipparcos data library based at the University at Strasbourg, France. There's no register feature and no need to give an email address if you don't need to. 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. U.G. Information regarding Metallicity and/or Mass is from the E.U. Zeta Herculis (ζ Her, ζ Herculis) is a multiple star system in the constellation Hercules. It has been known to produce widely incorrect figures. The visual binary Zeta Herculis (HR6212, HD150680) was discovered by Herschel in 1782, according to Lewis (1906). 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 Zeta 1 Reticuli and -69.7, -46.4, +16.8 km/s for Zeta 2 Reticuli. It has a combined apparent visual magnitude of 2.81, which is readily visible to the naked eye. Based upon parallax measurements, this system is located at a distance of about Template:Convert from the Earth. field images of the Zeta Herculissystem from. The Right Ascension is how far expressed in time (hh:mm:ss) the star is along the celestial equator. For Rutilicus, the location is 16h 41m 17.48 and +31° 36` 06.8 . The Declination is how far north or south the object is compared to the celestial equator and is expressed in degrees. 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 . Rutilicus is a F9IV subgiant star based on the spectral type that was recorded in the Hipparcos star catalogue. It is the brightest of the four stars that form the Keystone asterism. 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 . An easily visible third magnitude (3.16), this class K (K3) star shines at us from a distance of 370 light years, showing it to be quite luminous. Rutilicus estimated radius has been calculated as being 2.82 times bigger than the Sun. In the HR diagram, the star appears on … is the number of times that the star is from the Earth compared to the Sun. Apparent Magnitude is also known as Visual Magnitude. The diagram is the usual base for the classification of stars and is used to describe their evolution. Corncorde before it was retired was the fastest commercial airline across the Atlantic and only one that could do Mach 2. Rutilicus is a Subgiant Star type star. If you used the 1997 Parallax value, you would get an absolute magnitude of 2.64 If you used the 2007 Parallax value, you would get an absolute magnitude of 2.66. 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. [7], Component A has a stellar classification of F9 IV. Mach 1 is the speed of sound, Mach 2 is twice the speed of sound. The horizontal axis shows a variable related to surface temperature, such as the B-V color index, the spectral type, or the actual temperature. 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? [4129] eta Herculis is a G-class giant that acts as a gateway to Messier 13, the Great Cluster. (See Sloan Digital Sky Survey. w062: Temperature, Color, Bolometric-Correction Calibrations ---Astron. The star's effective temperature is 5,820 Kelvin which is hotter than our own Sun's effective Temperature which is 5,777 Kelvin. All stars like planets orbit round a central spot, in the case of planets, its the central star such as the Sun. Zeta Reticuli (Zeta Ret, ζ Reticuli, ζ Ret) is a wide binary star system in the southern constellation of Reticulum. ζ Herculis visual magnitude is 2.81. It is also known as M13 and its brightest star is called V11 which is bright red in color. [10][7], This system forms part of the Zeta Herculis moving group of stars. has done some calculations as to how long it will take going at differing speeds. The value comes from the Hipparcos Extended Catalog. 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. Zeta Reticuli (Zeta Ret, ζ Reticuli, ζ Ret) is a wide binary star system in the southern constellation of Reticulum.From the southern hemisphere the pair can be seen as a naked eye double star in very dark skies.Based upon parallax measurements, this system is located at a distance of about 39 light-years (12 parsecs) from the Earth.Zeta 2 Reticuli is orbited by a circumstellar debris disk.
