Best Answer

Titan can maintain its thick atmosphere due to its lower gravity, which allows it to hold onto gas molecules more effectively than Ganymede despite its smaller size. Additionally, the presence of organic compounds in Titan's atmosphere contributes to maintaining its atmospheric pressure.
