SUMMARY
Titan's atmosphere is maintained due to its extremely low temperatures, which prevent atmospheric particles from reaching escape velocity. The escape velocity on Titan is 2.6 km/s, while at approximately 100K, the typical energy of nitrogen molecules is around 240 m/s, significantly below the escape threshold. This indicates that Titan's atmospheric retention is not solely dependent on its mass but rather on the low thermal energy of its atmospheric particles. A substantial increase in temperature would be required to cause significant atmospheric loss.
