Message:

Tytan is smaller than for example Ganymede (Jupiter's moon) and in spite of this 
it's able to hold such a dense atmosphere of a pressure at the surface of about 
2 atm. As for Ganymede it has almost no atmosphere the same as the planets of 
the size. Isn't a density of atmosphares a function of the planets' masses?
