The solar ray will have an equation that is made up, because the solar ray it's self is fiction.

Here would be the general equation.

d^3-(stos*sr)-pi=t permutation 2

d=distance, in a certain unit that I have not thought of yet, most likely km

stos=surface temperature of star, in degrees Celsius

sr=solar radiation from nearest star, in millirads

pi=power input, in watts

T=time in seconds
