No need here for the Principle of Indifference. The principle is useful  
only in those rare cases in which one has zero prior information, as when  
one is in a state of total ignorance about the nature and properties of  
stars. Obviously that is not the case here.

In your inference above, you're extrapolating from the known to the  
unknown based on empirical data. If the purpose of your inference is to  
set a bayesian prior then you are proceeding as would an empirical  
bayesian.
