Using the most recent figures given by the 2007 Hipparcos data, the star is 34.95 light years away from us. It is also known as M13 and its brightest star is called V11 which is bright red in color. 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 distance of Kappa A Herculis is about 390 light-years while Kappa B Herculis may be up to 470 light-years away. The magnitude difference between the A-B pair is 1.52 ± 0.04 magnitudes (at 700 nm). If you want that in miles, it is about 206,986,399,389,794.91, based on 1 Ly = 5,878,625,373,183.61 miles. [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. A faint star will have a high number. 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. [ 3 ] You can decline to give a name which if that is the case, the comment will be attributed to a random 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. Zeta Herculis (ζ Her) - 35 light-years distance, is a testing double for large apertures. 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. w062: Temperature, Color, Bolometric-Correction Calibrations ---Astron. is the number of times that the star is from the Earth compared to the Sun. It is purely that the distance was recalculated. 100 Herculis has a curious colour contrast (yellow-white and blueish-white): 5.8, 5.8; 183º, 14.2". 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 . 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. Thanks to its high brightness, ζ Herculis is clearly visible when observed from locations with dark skyes, and should be … Luminosity is the amount of energy that a star pumps out and its relative to the amount that our star, the Sun gives out. Parallax measurements put it at a distance of about 35.0 light-years (10.7 parsecs) from Earth. The map was generated using Night Vision, an awesome free application by Brian Simpson. has done some calculations as to how long it will take going at differing speeds. An Astronomical Unit is the distance between Earth and the Sun. Both stars have severely low abundances of beryllium. 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 . 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. [9], The orbit and other information about the A-B binary is documented within the Washington Double Star Catalog. Hipparcos was a E.S.A. The star's effective temperature is 4,887 Kelvin which is cooler than our own Sun's effective Temperature which is 5,777 Kelvin The figure is derived at by using the formula from SDSS rather than peer reviewed papers. Magnitude, whether it be apparent/visual or absolute magnitude is measured by a number, the smaller the number, the brighter the Star is. Astroph. 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.
