Hertzsprung-Russel+Diagram

__Hertzsprung-Russell Diagram:__ Plots each star's absolute magnitude or brightness against its temperature and color on a graph.

Example of the graph below: Again, the diagram shows different charateristics of different suns as they go thoruogh their normal life cycle. For instance, lets pick a sun out from the graph to show how to figure out its absoulute magnitude, luminosity, temputure, and spectral class. Lets pick the white sun, that is in the middle of the graph, in its main seqence of life. If you look to that sun's left, you see the luminosity scale. Align the sun with that scale and you can tell that the sun that we picked out has a luminosity of about 5,000. You can also find out it's temputure, mangnitude, and spectral class doing that same thing with this graph. It is a very eas yway of studying the different stars throughout our universe.

The rest of thedifferent charateristics of the white sun we picked out is below: Effective tempurture: about 8,000 Absoulute Magnitude: +3 Spectral Class: A
