  • Exosphere - an overview | ScienceDirect Topics
    5 1 Exosphere The exosphere is an atmosphere so thin that its few atoms or molecules are unlikely to collide with one another In Earth's atmosphere, the exosphere is the highest part of the atmosphere where the density of gas molecules is very low At Mercury the exosphere is the only atmosphere, so the planet has what is called a surface-bounded exosphere, whose gas molecules collide with
  • Exosphere - an overview | ScienceDirect Topics
    The exosphere is defined as the outermost layer of the Earth's atmosphere, beginning near 500 km and extending far into space, where gas particles are so sparse that they follow ballistic trajectories and orbits AI generated definition based on: Encyclopedia of Atmospheric Sciences, 2003
  • Exosphere - an overview | ScienceDirect Topics
    The exosphere begins near 500 km and extends far out into space The number densities of the gases in the exosphere are so low that continuum fluid dynamics breaks down and gas particles follow ballistic trajectories and orbits The thermosphere is that rarefied region of our atmosphere where the temperature increases dramatically with altitude
  • Hybrid plasma simulations of the solar wind interaction with an . . .
    The amount of material instantaneously aloft and directly contributing to the exosphere drops from an initial ∼ 3% to ∼ 0 3%, and presumably continues to drop as photo-destruction and loss to the polar regions erodes the induced exosphere
  • Mercurys exosphere origins and relations to its magnetosphere and . . .
    Section 4 describes what is known about Mercury's dynamics driven by the coupling with Mercury's surface and with Mercury's magnetosphere Section 5 describes Mercury's exosphere–upper surface relations Section 6 gives some clues on the possible sources and sinks of Mercury's exosphere on a global scale and Section 7 concludes this paper
  • Mercury: the enigmatic innermost planet - ScienceDirect
    The extremely dynamic exosphere, which includes a number of species derived from Mercury’s surface, offers a novel laboratory for exploring the nature of the complex and changing interactions among the solar wind, a small magnetosphere, and a solid planet
  • Comparative deep Earth volatile cycles: The case for C recycling from . . .
    Crucial monitors of operation of deep Earth volatile cycles are the accumulated volatile masses in the exosphere, particularly when these are compared…
  • Kinetic modeling of sodium in the lunar exosphere
    In this paper we present a kinetic model of the sodium exosphere of the Moon as well as results of its validation against a set of ground-based and remote observations The unique characteristic of the model is that it takes the orbital motion of the Moon and the Earth into consideration and simulates both the exosphere as well as the sodium tail self-consistently The extended computational
  • Coupled H, H2, OH, and H2O lunar exosphere simulation framework and . . .
    The exosphere can be described as a collisionless atmosphere so tenuous that the mean free path of its constituent particles exceeds the length of their trajectories Unlike the Earth’s exosphere, its base rests directly on the lunar surface, making it a so-called surface-bounded exosphere
  • Lunar exosphere influence on lunar-based near . . . - ScienceDirect
    The potential effect of the lunar exosphere on the near-ultraviolet sky background emission is predicted for Lunar-based Ultraviolet Telescope (LUT: a…
