cluster’s HR diagram depends on age, and by matching a computer model of a cluster HR diagram to an observed HR diagram, it is possible to determine the age of the stars in the cluster. In general this can’t be done for a single isolated star outside of a cluster---we don’t know whether it was born last week or a billion years ago.

Such a plot is frequently called the Hertzsprung–Russell diagram, abbreviated H–R diagram. It is one of the most important and widely used diagrams in astronomy, with applications that extend far beyond the purposes for which it was originally developed more than a century ago. The Hertzsprung-Russell diagram (HR diagram) is one of the most important tools in the study of stellar evolution. The Hertzsprung-Russell Diagram Graphing or plotting data is an essential tool used by scientists. In attempting to make sense of data and see if two quantities are related we can plot them and seek trends. If we have a look at the two examples below the first shows two quantities, X and Y that an object may have. The H-R diagram is a chart that every astronomy student learns early on.
