MODEL OF TITAN'S ATMOSPHERE
As on Earth, the dominant atmospheric constituent in Titan's atmosphere is nitrogen. Methane represents about six percent of the atmosphere. Titan's surface pressure is 1.6 times that on Earth, despite Titan's smaller size. The surface temperature was found by Voyager to be 95 degrees Kelvin (minus 289 degrees Fahrenheit). The opacity of Titan's atmosphere is caused by naturally produced photochemical smog. Voyager's infrared spectrometer detected many minor constituents produced primarily by photochemistry of methane, which produces hydrocarbons such as ethane, acetylene and propane. With Titan's smoggy sky and distance from the Sun, a person standing on Titan's surface in the daytime would experience a level of daylight equivalent to about 1/1,000th the daylight at Earth's surface. |
