Answer:
A. It is very cold at Titan. Cold gases are more easily held in place by gravity, so although Titan is the size of Mercury, it is able to cling to this gold gas.
Explanation:
Titan is among Saturn's numerous moons the largest one. It is remarkable for many reasons but the most intriguing one is his atmosphere.
At first, all planets, as well as big moons, have an atmosphere. But there are many factors that can lead to its loss, just as <em>Mars, a planet larger than Titan, lost its atmosphere.</em>
The problem with Mars is it is too close to the Sun. The temperature was high and the molecules managed to escape its gravity.
But Saturn and Titan are really far and the temperatures are low. <em>The molecules are not able to move fast enough</em> and this way Titan manages to hold on to its atmosphere.
