  2. Exosphere - Wikipedia

    en.wikipedia.org/wiki/Exosphere

    The exosphere is a thin, atmosphere-like volume surrounding a planet or natural satellite where molecules are gravitationally bound to that body, but where the density is so low that the molecules are essentially collision-less. [1]

  3. Atmosphere of Earth - Wikipedia

    en.wikipedia.org/wiki/Atmosphere_of_Earth

    The exosphere is the outermost layer of Earth's atmosphere (though it is so tenuous that some scientists consider it to be part of interplanetary space rather than part of the atmosphere). It extends from the thermopause (also known as the "exobase") at the top of the thermosphere to a poorly defined boundary with the solar wind and ...

  4. Is anyone deliberately tampering with our atmosphere? If so ...

    Five distinct layers have been identified, the troposphere, stratosphere, mesosphere, thermosphere and exosphere. With solid data, scientists can better understand the extremely complex systems ...

    The lunar atmosphere is extremely thin and technically classified as an exosphere, meaning atoms do not collide with each other because their numbers are so sparse, in contrast to Earth's thick ...

  6. Extraterrestrial atmosphere - Wikipedia

    en.wikipedia.org/wiki/Extraterrestrial_atmosphere

    The thermosphere and exosphere begin at around 95 kilometres, eventually reaching the limit of the atmosphere at about 220 to 250 km. The air pressure at Venus' surface is about 92 times that of the Earth.

  7. Upper atmosphere - Wikipedia

    en.wikipedia.org/wiki/Upper_atmosphere

    The exosphere, which on Earth lies between the altitudes of about 700 kilometres (435 mi) and 10,000 kilometres (6,200 mi) The ionosphere, an ionized portion of the upper atmosphere which includes the upper mesosphere, thermosphere, and lower exosphere and on Earth lies between the altitudes of 48 and 965 kilometres (30 and 600 mi)

  8. The moon has entered a new epoch, scientists say - AOL

    The moon also has features like a delicate exosphere composed of dust and gas and ice inside permanently shadowed areas that are vulnerable and could be disturbed by continued explorations, the ...

  9. Thermopause - Wikipedia

    en.wikipedia.org/wiki/Thermopause

    As a lower boundary for the exosphere this boundary is also called the exobase. [ 1 ] The exact altitude varies by the energy inputs of location, time of day, solar flux, season, etc. and can be between 500 and 1,000 kilometres (310 and 620 mi) high at a given place and time because of these.
