This is where the Boltzmann law comes in to play. In order to calculate the emissivity of an object, you first need bot: the power of emissions from the target object, and the Power that would be emitted by a black body of the same temperature. This value can be procured using the Stefan Boltzmann Law of Radiation. This is where the Boltzmann law comes in to play.

Albedo, however, is a far simpler quantity, relying only on the input and output energies of the object. Albedo, however, is a far simpler quantity, relying only on the input and output energies of the object.
## Inverse Square Law and Apparent brightness
If $b$ is the Power experienced at a radius $r$:
$$
b=\frac{L}{4\pi r^2}
$$
The above is true when $L$ is procured from the source, most likely using the Boltzmann's law.
