Its nothing to fear as the stars are so far apart, they won't collide in our life-time, if ever. It is the brightest of the four stars that form the Keystone asterism. The map was generated using Night Vision, an awesome free application by Brian Simpson. The visual binary Zeta Herculis (HR6212, HD150680) was discovered by Herschel in 1782, according to Lewis (1906). All stars like planets orbit round a central spot, in the case of planets, its the central star such as the Sun. 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. Based on the spectral type (F9IV) of the star, the star's colour is yellow to white . It has a combined apparent visual magnitude of 2.81, which is readily visible to the naked eye.

You can decline to give a name which if that is the case, the comment will be attributed to a random star. [7], Component A has a stellar classification of F9 IV. The star's effective temperature is 4,887 Kelvin which is cooler than our own Sun's effective Temperature which is 5,777 Kelvin Magnitude, whether it be apparent/visual or absolute magnitude is measured by a number, the smaller the number, the brighter the Star is. 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. Rutilicus is a Binary or Multiple star system. Eta Herculis is a G-Type star. Both stars are solar analogs that share similar characteristics with the Sun. The time it will take to travel to this star is dependent on how fast you are going. The star's effective temperature is 5,820 Kelvin which is hotter than our own Sun's effective Temperature which is 5,777 Kelvin. Luminosity is the amount of energy that a star pumps out and its relative to the amount that our star, the Sun gives out. Rutilicus is a F9IV subgiant star based on the spectral type that was recorded in the Hipparcos star catalogue. 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.
