Titan’s atmosphere is unbreathable, but if you were standing on Titan … Titan may become warmer in the future. The probe touched down on a frozen surface littered with rounded pebbles. A slightly elevated temperature is observed at 65 S in the relatively cloud-free zone between the mid-latitude and southern cloud regions. 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. 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. 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. But rather than water, with surface temperatures of around –180ºC, the fluid involved here is methane, a simple organic compound. Future temperature. This is a much smaller contrast than exists between Earth’s warmest and coldest temperatures, which can vary by more than 200 degrees … La température à la surface de Titan est d’environ 94 K (−179 °C). Titan. Clouds of nitrogen are not present, apparently because temperatures are always above the condensation point of nitrogen. 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 … 1981), so that we now have a baseline of more than a Titan … 1981; Samuelson et al. Titan's surface is half covered with frozen water and the rest is bare rock. Titan has a dense atmosphere of 95 percent nitrogen and 5 percent methane at 1.5 times the air pressure on Earth. 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. Surface Temperature:-179 °C: Discovery Date: March 25, 1655: Discovered By: Christiaan Huygens Key words: planets and satellites: individual (Titan) – planets and satellites: surfaces – radiation mechanisms: 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. Initially thought to be rocks or ice blocks, they are more pebble-sized. Surface temperatures were first measured by Voyager in 1980 November (Flasar et al. 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. À cette température, la glace d’eau ne se sublime pas et l’atmosphère est presque entièrement dénuée de vapeur d'eau. The data showed Titan to have a thick atmosphere of approximately the correct temperature and composition to support them.
