Web28 jun. 2024 · 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. That’s almost as wide as Earth itself. The exosphere is really, really big. That means that to get to outer space, you have to be really far from Earth. WebSince the tropopause responds to the average temperature of the entire layer that lies underneath it, it is at its maximum levels over the Equator, and reaches minimum heights over the poles. On account of this, the coolest layer in the atmosphere lies at about 17 km over the equator.

WebWhile definitions based on altitude are inherently ambiguous, most of them fall within the range specified by an orbit period of 128 minutes because, according to Kepler's third law, this corresponds to a semi-major axis of 8,413 km (5,228 mi). WebOne 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. WebAnswer (1 of 17): The karman line is the frontier of the atmosphere. Based on calculations, it was defined to be at 100 kilometer of altitude, or 62 miles. The logic behind it is that a plane would need to go faster than orbital speed at … flowers swinton manchester
