Luminosity of Stars Calculator

The absolute magnitude of a star is a simple way of describing its luminosity. Luminosity, L, is a measure of the total amount of energy radiated by a star or other celestial object per second. A force that tends to pull a particle or body toward the axis around which it rotates.


Luminosity of Stars Calculator

Luminosity of star Calculation:
Distance : in meters
Brightness: Brightness in W
Actual Luminosity or brightness:

 
   
  


Formula Used to calculate luminosity of stars:

L=4*Pi*d2*b

L = Luminosity of the star
d = Distance in meters
b = Brightness in W/m2
