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]
13 maj 2024 · The exosphere is the outermost layer of the Earth’s atmosphere, where most satellites orbit. The exosphere denotes the end of our atmosphere and the beginning of outer space, though there is not a definitive top altitude where the exosphere ends.
The exosphere, situated at the outermost fringes of the atmosphere, is where the transition from Earth’s gaseous envelope to the vacuum of outer space occurs. It’s also home to a sparse collection of atoms and molecules that gradually dissipate into the void beyond.
The exosphere is the uppermost region of Earth's atmosphere as it gradually fades into the vacuum of space. The air in the exosphere is extremely thin - in many ways, it is almost the same as the airless void of outer space.
exosphere, outermost region of a planet’s atmosphere, where molecular densities are low and the probability of collisions between molecules is very small. The base of the exosphere is called the critical level of escape because, in the absence of collisions, lighter, faster-moving atoms such as hydrogen and helium may attain velocities that ...
2 paź 2019 · Exosphere. Located between about 700 and 10,000 kilometers (440 and 6,200 miles) above Earth’s surface, the exosphere is the highest layer of Earth’s atmosphere and, at its top, merges with the solar wind.
