3. Mars’ Mean Surface Temperature calculation.
Tmean.mars
Surface temp..Tmin..Tmean..Tmax
Kelvin...................130.K.....210.K....308.K
(1/R²) = (1/1,524²) = 1/2,32
Mars has 2,32 times less solar irradiation intensity than Earth has
Mars’ albedo: amars = 0,25
Mars performs 1 rotation every 1,028 day
For Mars
N = 1 /1,028 = 0,9728 rotations /day (or 0,9728 marsian day /per an earthen day)
Mars is a rocky planet, Mars’ surface irradiation accepting factor: Φmars = 0,47
cp.mars = 0,18cal/gr oC, on Mars’ surface is prevalent the iron oxide.
β = 150 days*gr*oC/rotation*cal – ( the Rotational Warming Factor constant ).
σ = 5,67*10⁻⁸ W/m²K⁴, the Stefan-Boltzmann constant.
Mars' Mean Surface Temperature Equation is:
Tmean.mars = [ Φ (1-a) So (1/R²) (β*N*cp)¹∕ ⁴ /4σ ]¹∕ ⁴
Tmean.mars = [ 0,47 (1-0,25) 1.361 W/m²*(1/2,32)*(150*0,9728*0,18)¹∕ ⁴ /4*5,67*10⁻⁸ W/m²K⁴ ]¹∕ ⁴ =
=( 2.066.635.457,46 )¹∕ ⁴ = 213,21 K
Tmean.mars = 213,21 K
The calculated Mars’ mean surface temperature
Tmean.mars = 213,21 K is only by 1,53% higher than that measured by satellites
Tsat.mean.mars = 210 K !

So, we know how to calculate the PLANETARY TEMPERATURES.
After the initial insights, in the present research we demonstrate a typical scientific analysis.
And we have calculated the planet mean surface temperatures for all planets and moons. The calculations are in the next pages of the present site.
