Major Constituents measured in percentage ( % )	N2 (Nitrogen) 82-99 % CH4 (Methane) 1-6 22Ne (Neon) Primordial ??? % *40Ar (Argon) Radiogenic ??? % *36Ar (Argon) Primordial < 1-6 % * isotope of Argon deduced indirectly click here for more on Argon on page 206 | 40 Argon | Argon (physicsforme) There is a theoretical expectation that argon is present in the atmosphere, but there has been no direct detection of this atom. However, because it is difficult to detect, argon might still be present in significant amounts (i.e. mole fractions of <10%).

Other interesting characteristics: Titan's atmosphere was first detected spectroscopically in 1944 by the Dutch American astronomer Gerard P. Kuiper , who found evidence of the absorption of sunlight by methane. One Titan year is equal to 30 Earth Years Titan's current chemistry is believed to resemble how Earth's pre-biological chemistry was. Earth has the advantage of our Sun unlike Titan. Yet Titan's chemistry and atmosphere is more diverse and mysterious even with the Cassini mission and the Huygen's probe which landed on Titan in 2005 Titan has seasons too The Titanian Seasons Turn, Turn, Turn (JPL) Both Titan and Earth have a greenhouse effect Titan also has continents and oceans as determined through radar, confirmed from Cassini & Huygen's probe Also liquid hydrocarbon lakes, cryovolcanoes Methane exists in its triple point much like our water in solid, liquid and gas states image Second largest moon in our Solar System (Jupiter's Ganymede is the largest) Additional facts

The video that changed my life mesmerizing me to research Titan

This is the video about Voyager's 1 results of Saturn highlighting Titan that changed my life!!! Toby Owen who was my inspiration who I communicated with and met at JPL talks about Hydrogen Cyanide in this video.
