### A Blackbody Planet Surface Equilibrium Temperature (A Blackbody Effective Temperature)

A Blackbody Planet Surface Equilibrium Temperature (A Blackbody Effective Temperature)

A blackbody planet surface is meant as a classical blackbody surface approaching.

Here are the blackbody's properties:

Blackbody absorbs the entire incident on the blackbody's surface radiation.

Blackbody is considered only as a blackbody's surface physical properties.

Blackbody does not consist from any kind of a matter.

Blackbody has not mass. Thus blackbody has not a specific heat.

Blackbody's cp = 0.

Blackbody has a surface dimensions. So blackbody has the radiated area and blackbody has the emitting area.

The whole blackbody's surface area is the blackbody's emitting area.

The blackbody's surface has an infinitive conductivity.

All the incident on the blackbody's surface radiative energy is instantly and evenly distributed upon the whole blackbody's surface.

The radiative energy incident on the blackbody's surface the same very instant the blackbody's surface emitts this energy away.

The emittance temperature the blackbody's surface has according to the Stefan-Boltzmann Law is:

Te = (Total incident W /Total area m² *σ)¹∕ ⁴ K

σ = 5,67*10⁻⁸ W/m²K⁴, the Stefan-Boltzmann constant.

** The faster a planet rotates (n2>n1) the higher is the planet’s average (mean) temperature T↑mean:**

** Tmin↑→ T↑mean ← T↓max**
