[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. Luminosity is the amount of energy that a star pumps out and its relative to the amount that our star, the Sun gives out. is from Simbad, the Hipparcos data library based at the University at Strasbourg, France. It should not be taken as though the star is moving closer or further away from us. Information regarding Metallicity and/or Mass is from the E.U. (See Sloan Digital Sky Survey. It has a combined apparent visual magnitude of 2.81,[2] which is readily visible to the naked eye. It is purely that the distance was recalculated. Now click on 95 Herculis on the map. The number of A.U. 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. 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). Astroph. There's no register feature and no need to give an email address if you don't need to. ζ Herculis (zeta Herculis) ζ Herculis is a variable and double hypergiant star in the constellation of Hercules. 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. The Declination is how far north or south the object is compared to the celestial equator and is expressed in degrees. Using the 2007 distance, the star is roughly 2,211,143.32 Astronomical Units from the Earth/Sun give or take a few. The color of a star reflects the temperature of its surface, from tepid red-hot (far right) to zeta Herculis is another double star composed of a subgiant and a faint companion star. 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. 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. Both stars have severely low abundances of beryllium. Rutilicus is a Subgiant Star type star. [10] Two astrometric studies have failed to detect a third component to the A-B binary. Colour and Temperature Based on the star's spectral type of G8III, Kornephoros's colour and type is yellow giant star. The magnitude difference between the A-B pair is 1.52 ± 0.04 magnitudes (at 700 nm). Its primary mission was to visit Pluto which at the time of launch (2006), Pluto was still a planet. You can decline to give a name which if that is the case, the comment will be attributed to a random star. The Sun's radius is 695,800km, therefore the star's radius is an estimated 1,960,045.73.km. Go anywhere, anytime with tires built to dominate off-road and deliver efficiency on them. Zeta Herculis (ζ Her) - 35 light-years distance, is a testing double for large apertures. more orange in color. The value comes from the Hipparcos Extended Catalog. It has a combined apparent visual magnitude of 2.81, which is readily visible to the naked eye. [10][7], This system forms part of the Zeta Herculis moving group of stars. The time it will take to travel to this star is dependent on how fast you are going. The New Horizons space probe is the fastest probe that we've sent into space at the time of writing. 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.

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. [3] It has about 2.6 times the radius of the Sun and 1.45 times the Sun's mass. The visual binary Zeta Herculis (HR6212, HD150680) was discovered by Herschel in 1782, according to Lewis (1906). The Right Ascension is how far expressed in time (hh:mm:ss) the star is along the celestial equator. The constellations that we see today will be different than they were 50,000 years ago or 50,000 years from now. 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. It spins at 1.74 km/s. A faint star will have a high number. Our own Sun is the brightest star and therefore has the lowest of all magnitudes, -26.74. The star's effective temperature is 4,887 Kelvin which is cooler than our own Sun's effective Temperature which is 5,777 Kelvin 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. Using the most recent figures given by the 2007 Hipparcos data, the star is 34.95 light years away from us. All messages will be reviewed before being displayed. The location of the subgiant star in the night sky is determined by the Right Ascension (R.A.) and Declination (Dec.), these are equivalent to the Longitude and Latitude on the Earth. Rutilicus Facts. Rutilicus is a F9IV subgiant star based on the spectral type that was recorded in the Hipparcos star catalogue. The information was obtained as of 12th Feb 2017. [4126] pi Herculis, also known as Fudail ("excellent in character"), is an orange giant. 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. The map was generated using Night Vision, an awesome free application by Brian Simpson. Zeta Herculis is a multiple star with a combined apparent magnitude of 2.81, only 35 light years distant from Earth. Parallax measurements put it at a distance of about 35.0 light-years (10.7 parsecs) from Earth.
