A Method to Determine the Mean Temperature at the Planet Surface
The escape time of a given species of particles in the planetary atmosphere is related to atmospherictemperature. The mean temperature at the planet surface may be inferred from the escape of a given kind of particles inthe planetary atmosphere. For example, CH4 escaping from the Pluto atmosphere results in the variation of its partialpressure and escape time, then the mean temperature at the Pluto surface, 42.2 K, is got on the basis of it.
