A slightly elevated temperature is observed at 65 S in the relatively cloud-free zone between the mid-latitude and southern cloud regions. Titan has a dense atmosphere of 95 percent nitrogen and 5 percent methane at 1.5 times the air pressure on Earth. À cette température, la glace d’eau ne se sublime pas et l’atmosphère est presque entièrement dénuée de vapeur d'eau. 1981; Samuelson et al. Titan’s atmosphere is unbreathable, but if you were standing on Titan … Surface temperatures were first measured by Voyager in 1980 November (Flasar et al. Future temperature. The data showed Titan to have a thick atmosphere of approximately the correct temperature and composition to support them. 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. But rather than water, with surface temperatures of around –180ºC, the fluid involved here is methane, a simple organic compound. The possibility that there were seas on Titan was first suggested based on data from the Voyager 1 and 2 space probes, launched in August and September 1977. 1981), so that we now have a baseline of more than a Titan … Key words: planets and satellites: individual (Titan) – planets and satellites: surfaces – radiation mechanisms: This is a much smaller contrast than exists between Earth’s warmest and coldest temperatures, which can vary by more than 200 degrees … Five to six billion years from now, as the Sun becomes a red giant, surface temperatures could rise to ~200 K (−70 °C), high enough for stable oceans of a water–ammonia mixture to exist on its surface. Titan's surface is half covered with frozen water and the rest is bare rock. Like Earth, the surface temperature of Titan, which is usually in the chilly mid-90 kelvins (around minus 288 degrees Fahrenheit), was significantly warmer in the late afternoon than around dawn. Surface Temperature:-179 °C: Discovery Date: March 25, 1655: Discovered By: Christiaan Huygens Clouds of nitrogen are not present, apparently because temperatures are always above the condensation point of nitrogen. The probe touched down on a frozen surface littered with rounded pebbles. Initially thought to be rocks or ice blocks, they are more pebble-sized. Titan. It has a mean surface temperature of 94 K. The exploration of Titan was conducted by Cassini-Huygens (Cassini Orbiter, Huygens Probe), which is a joint NASA/ESA/ASI unmanned space mission intended to … Titan may become warmer in the future. This is the first coloured view of Titan's surface, following processing to add reflection spectra data, gives a better indication of the actual colour of the surface. A troposphere analogous to Earth’s extends from Titan’s surface to an altitude of 42 km (26 miles), where a minimum temperature of 71 K (−332 °F, −202 °C) is reached. La température à la surface de Titan est d’environ 94 K (−179 °C).
