Why does Titan have an atmosphere similar ot Earth's?

Question

Why, because of the cold, gravity, heavy inert gasses? Someone explain why please.

Answer 1

The composition of Titan's atmosphere is not the same as Earth's, in fact it has a lot of methane which is stable as a gas and liquid at such a cold temperature (in fact, titan might have methane rain and methane lakes). But Titan has a thick atmosphere because it is far away from the sun, and receives a lot less solar energy than the Earth. Solar energy heats the gas in the atmosphere of a planet/moon and gives it thermal energy.
Depending on the size (mass and radius) of the planet/moon, there is a certain escape velocity needed to evaporate into space. Titan's surface gravity is about 15% of Earth's, so you wouldn't expect it to have a thick atmosphere, and it wouldn't if it were at the same distance from the Sun as the Earth is, just like the moon has no atmosphere.
However, because Titan is so far away, the atmosphere there has less thermal energy than the Earth's because the Sun's energy is weaker there. Because it is colder, the gases in the atmosphere do not have enough energy to reach the escape velocity and evaporate into space.
Basically, Titan has a thick atmosphere because it is cold that far away from the Sun and it is much easier to hold onto a cold atmosphere than a warm one.

Answer 2

It's the distance from the sun. Saturn doesn't provide sufficient heat for Titan's atmosphere to leak into space. If it were in the same orbit of Earth, it would have lost the atmosphere it has long ago.
The atmosphere is primarily hydrogen with methane snow and 'rivers and lakes'.
Ironically, if we were to try to colonize it, the pressure is sufficient enough to not need full space suits. The temperature however is an average of a negative 178 below zero so maybe the suits would be a good thing after all!

Answer 3

As of maximum suitable now, none. the great kicker right this is the nitrogen and oxygen interior the ambience. the closest yet another planet involves having a matching nitrogen volume is Mars, with in common terms 3% of its environment composed of Nitrogen. besides the shown fact that, that's believed that Venus has a matching environment to Earth while it replaced into forming, and one in each and every of Saturn's moons, Titan, has a many times Nitrogen environment (albeit no oxygen).

Answer 4

wow thats neat ! I never knew Titan had the same atmosphere! cool!!!

way coool !

Answer 5

good question. our greatest minds are still trying to find the answer, too.
