Facts about Titan's Nitrogen Atmosphere
- 08
Winds in Titan's nitrogen atmosphere reach speeds of 10 to 100 meters per second, with jet streams driven by solar heating differences between its equator and poles.
- 07
Below Titan's dense nitrogen atmosphere, surface pressure measurements indicate liquid methane-ethane seas exist in polar regions, creating Earth's only known extraterrestrial oceans of hydrocarbons rather than water.
- 06
Titan's nitrogen atmosphere escapes to space at a rate of approximately 100 grams per second due to solar wind and magnetospheric interactions.
- 05
Organic haze layers in Titan's nitrogen atmosphere create a thick orange smog that absorbs ultraviolet radiation and reaches altitudes exceeding 200 kilometers above the surface.
- 04
Titan's nitrogen atmosphere produces a temperature inversion in its upper stratosphere, where methane absorption of solar radiation creates a warm layer around 200 kilometers altitude.
- 03
Cassini-Huygens measurements in 2005 detected methane and other organic compounds in Titan's nitrogen atmosphere, forming complex chemistry that produces tholins and prebiotic molecules.
- 02
Nitrogen comprises roughly 98.4 percent of Titan's atmosphere, making it the only known moon with a substantial nitrogen-dominated atmosphere.
- 01
At 1.5 times Earth's atmospheric pressure, Titan's nitrogen-rich atmosphere is denser than Earth's air at sea level.
