The upper boundary of the exosphere can be defined as the distance at which the influence of solar radiation pressure on atomic hydrogen exceeds that of Earth's gravitational pull. This happens at half the distance to the Moon or somewhere in the neighborhood of 200,000 kilometres (120,000 mi).
28 cze 2019 · The exosphere is the outermost layer of Earth’s atmosphere, about 6,200 miles (10,000 kilometers) thick. It’s the very edge of our atmosphere and separates it from outer space.
One definition of the outermost limit of the exosphere places the uppermost edge of Earth's atmosphere around 190,000 km (120,000 miles), about halfway to the Moon. At this distance, radiation pressure from sunlight exerts more force on hydrogen atoms than does the pull of Earth's gravity.
Where is the exosphere? The exosphere is the outermost layer of the atmosphere. It’s part of the thermosphere between about 500 km to 190,000 km (which is roughly halfway to the Moon). The lower part of the exosphere is the exobase.
Dolna granica egzosfery Ziemi, termopauza, która oddziela ją od termosfery, znajduje się na wysokości ok. 500 km. Umowna granica przestrzeni kosmicznej, Linia Kármána, znajduje się 400 km niżej w termosferze.
21 lip 2019 · The exosphere is the outermost layer of the Earth's atmosphere, located above the thermosphere. It extends from about 600 km until it thins out to merge with interplanetary space. This makes the exosphere about 10,000 km or 6,200 miles thick or about as wide as the Earth. The top boundary of Earth's exosphere extends about halfway to the Moon.
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.
