Earth's exosphere, energetic neutral atoms (ENA) and magnetosphere. In principle, the exosphere covers distances where particles are still gravitationally bound to Earth, i.e. particles still have ballistic orbits that will take them back towards Earth.
Egzosfera – najbardziej zewnętrzna warstwa atmosfery planety lub księżyca. Egzosfera zwana jest inaczej sferą rozpraszania, sferą dyssypacji. Charakterystyka. Gazy tworzące egzosferę są rozrzedzone do tego stopnia, że prawdopodobieństwo zderzenia ich cząsteczek, poruszających się z dużymi prędkościami, jest bardzo małe.
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.
28 cze 2019 · The exosphere is the very edge of our atmosphere. This layer separates the rest of the atmosphere from outer space. It’s about 6,200 miles (10,000 kilometers) thick.
The Earth’s exosphere begins about 500 km (300 miles) above the terrestrial surface and extends out through the magnetosphere and beyond to the interplanetary medium. Temperatures in the Earth’s exosphere remain constant with altitude, averaging about 1500 K.
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. Molecules found here are of extremely low density, so this layer doesn’t behave like a gas, and particles here escape into space.
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.
