### The planet's effective temperature Te = [ Φ (1-a) S / 4 σ ]¹∕ ⁴

**We know, that the on the smooth without atmosphere planet's surface the "absorbed" incident solar flux fraction is Φ (1 - a) S, here the solar flux is weakened by the combined reflection of albedo and Φ and what is left to "absorb" is Φ (1 - a) S and it is the basis for estimating the planet's theoretical uniform emission temperature so the Te which represents the planet's emission temperature calculated by the blackbody assumptions uniform theoretical planet's emission temperature has changed now, the old "blackbody" equation transforms as:**

** Te = [ Φ (1-a) S / 4 σ ]¹∕ ⁴ **

**Planet ......Te........ Tmean...... Tsat......... N **

**............emission equation measured rot /day**

**.........theoretical..... new.... from orbit **

**Mercury.. 362 K.... 323,14 K.. 340 K... 1 /176**

** Earth....... 211 K.... 288,36 K.. 288 K....... 1 **

**Moon .......224 Κ.... 221,74 Κ.. 220 Κ.... 1 /29,5 **

*Mars ........174 K.... 213,21 K.. 210 K .......1*

**And we observe here that Te depended only on solar flux and albedo, but with the same Φ = 0,47 gradually subsides from Mercury to Mars from 362 K to 174 K, when Eath and Moon, having the same solar flux differ because Earth has a higher albedo.**
