Io /Enceladus satellite measured mean temperatures comparison 110 K / 75 K

 

Here we have some two, far away from the sun moons, satellite measured mean temperatures comparison.

Io is Jupiter's moon and Enceladus is Saturn's moon.

Both have solar irradiation accepting factor Φ = 1 ( rock type surface, heavy cratered )

Here we have a complete comparison coefficient with all the terms (albedo, solar flux, N and cp) and with all the terms being different.

Io's mean radius is 1.822 km

Enceladus's mean radius is 252,1 +- 0,2 km

 

Comparison coefficient

[ (1 - a) S (N*cp)¹∕ ⁴ ]¹∕ ⁴

 

Io

Tmean = 110 K

[ (1- 0,63) 50,37 (0,5559*0,145)¹∕ ⁴ ]¹∕ ⁴ = 1,77518

 

Enceladus

Tmean = 75 K

[ (1- 0,85) 14,84 (0,7299*1)¹∕ ⁴ ]¹∕ ⁴ = 1,19766

 

Let's compare

110 K / 75 K = 1,4667

1,77518 /1,19766 = 1,4822

 

There is only 1% difference!
