The exosphere is a thin, atmosphere-like volume surrounding a planet or natural satellite. Its molecules are gravitationally bound to that body. The density is so low that the molecules are essentially collisionless. [1]
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]
What is the exosphere and what role does it play in protecting Earth from harmful radiation? The exosphere is the outermost layer of Earth’s atmosphere, extending from about 500 km to 10,000 km above the surface.
28 cze 2019 · The exosphere is the outermost layer of our atmosphere. “Exo” means outside and is the same prefix used to describe insects like grasshoppers that have a hard shell or “exoskeleton” on the outside of their body. The exosphere is the very edge of our atmosphere.
Egzosfera stanowi płynną strefę przejściową między atmosferą a otwartą przestrzenią kosmiczną, niektórzy naukowcy traktują ją wręcz jako część przestrzeni kosmicznej [2]. Najprostszą formą atmosfery, którą mogą mieć najmniejsze ciała planetarne zdolne utrzymać otoczki gazowe, jest egzosfera sięgająca do powierzchni.
What is the exosphere? This is the layer of the atmosphere that you can see in satellite images of the Earth as the fuzzy blue layer surrounding our planet. The exosphere is home to many weather satellites, which are in ‘low-Earth orbit’ or ‘medium-Earth orbit’.
3 maj 2022 · Exosphere. The exosphere is the outer layer of the Earth’s atmosphere. It extends from the thermopause or exobase (500–1000 km; 310–620 mi; 1,600,000–3,300,000 ft) to around 100,000 km (6,200 mi; 33,000,000 ft). At this point, the atmosphere merges into the solar wind.
