Experimental data determined that an object radiates electromagnetic energy at a rate $P=eA{T}^4$ where $e$ is the emissivity, $$ is the Stefan$-$Boltzmann constant, $A$ is the surface area, and $T$ is the Kelvin temperature. An idealized dense object with $e=1$ is known as a blackbody, and its properties include energy that falls on it$,$ thus its name. all radiative
