How to calculate apparent brightness in relation to the sun

I know that we can determine the apparent brightness of an object in our solar system using the following formula:

$$B=\frac{A\cdot L_S\cdot R^2}{D^2\cdot d^2}$$

$$B$$ = Brightness of observed object in watts
$$A$$ = Albedo of observed object
$$L_S$$ = Luminosity of the Sun in watts
$$R$$ = Radius of the observed object in meters
$$D$$ = Distance between the Sun and the observed object in meters
$$d$$ = Distance between the Earth and the observed object in meters

However, I find this isn't helpful in visualizing the brightness in your mind. I was wondering what modifications would be needed to this formula to make the result relative to the sun.

• You could simply divide by the apparent brightness of the sun which would give you a result in percent of the sun's brightness. – Jonas Feb 27 at 10:40
