Credit to @Kepekley23: This point seems to be a common feat in fiction with a pocket realm having stars to such a average distance so I wanted to do the calculation

Using Kep's calculation basis for the distance between the average star distance that the human eye can see couple with the average numbers of stars which the human eye can see on a clear sky which is around 2500 along with the average star size:

The radius of the sun for the average star: 695510000 m

4*5.693e41*(1.894e19/695510000)^2 = 1.688e63 joules, (Multi-Solar System level
