Web21 mrt. 2024 · This thin exosphere means that the temperature on the planet Mercury can vary drastically, from over 400°c at one point to as cold as -180°c on the dark side of the planet. So, it’s clear to see why Mercury’s lack of atmosphere has left it as the second hottest planet as opposed to being the first. The most common molecules within Earth's exosphere are those of the lightest atmospheric gases. Hydrogen is present throughout the exosphere, with some helium, carbon dioxide, and atomic oxygen near its base. Because it can be hard to define the boundary between the exosphere and outer space (see "Upper boundary of Earth" at the end of this section), the exosphere may be considered a part of the interplanetary medium or outer space. The height of t…

Web2 nov. 2024 · Exosphere. The exosphere is the layer above the thermosphere. This is the top of the atmosphere. The exosphere has no real upper limit; it just gradually merges with outer space. Gas molecules are very far apart in this layer, but they are really hot. Earth’s gravity is so weak in the exosphere that gas molecules sometimes just float off into ...
