If gas molecules satisfy the formula above, their kinetic energy is much less than the depth of potential well of planet's gravity, therefore they cannot escape. So the planet will keep its atmosphere.23 Dec 2014
Is Titan losing its atmosphere?
Cassini observations of Titan's atmosphere are revealing the mechanisms by which Titan's atmosphere is being lost to space. Titan has a weak cold trap which hangs onto only some of the atmospheric methane. Thus, most methane is not trapped through freezing in the atmosphere.
Does Titan have a permanent atmosphere?
The atmosphere of Titan is the dense layer of gases surrounding Titan, the largest moon of Saturn. It is the only thick atmosphere of a natural satellite in the Solar System. Titan's lower atmosphere is primarily composed of nitrogen (94.2%), methane (5.65%), and hydrogen (0.099%)….Atmosphere of Titan.

How does Titan still have an atmosphere?
"Because Titan is the only moon in our solar system with a substantial atmosphere, scientists have wondered for a long time what its source was," Miller said. "The main theory has been that ammonia ice from comets was converted, by impacts or photochemistry, into nitrogen to form Titan's atmosphere.
Will Titan ever be habitable?
Additionally, Titan's rivers, lakes and seas of liquid methane and ethane might serve as a habitable environment on the moon's surface, though any life there would likely be very different from Earth's life.
Is Titan’s atmosphere thicker than Mars?
Mars lost most of its atmosphere long ago to the solar wind due to a lack of a meaningful electromagnetic field. Saturn's Titan has an atmosphere denser than Earth's, yet Titan is a smaller body than Mars.
Is Titan’s atmosphere toxic?
SATURN'S giant moon Titan has an atmosphere a thousand times more poisonous than thought. Titan's thick atmosphere is made of nitrogen and methane, and the action of UV light forms many organic compounds, such as deadly hydrogen cyanide. In 1980 the Voyager spacecraft found only a trace of cyanide.
What is the lowest temperature ever recorded on Titan?
Although it moves in latitude, the maximum measured temperature on Titan remains around -292 degrees Fahrenheit (-179.6 degrees Celsius, 93.6 Kelvin), with a minimum temperature at the winter pole only 6 degrees Fahrenheit (3.5 degrees Celsius or Kelvin) colder.
Could Europa have life?
The type of life that might inhabit Europa likely would not be powered by photosynthesis – but by chemical reactions. Europa's surface is blasted by radiation from Jupiter. That's a bad thing for life on the surface – it couldn't survive. But the radiation may create fuel for life in an ocean below the surface.
Does Titan moon have oxygen?
Titan also has a presence of organic molecules that contain carbon and hydrogen, and that often include oxygen and other elements similar to what is found in Earth's atmosphere and that are essential for life.
