19 paź 2023 · Note that the atmosphere still exists beyond the Karman line; in fact, tiny particles of the exosphere (the outermost layer of the atmosphere) can be found 10,000 kilometers above the surface of Earth! From that perspective, the International Space Station, which orbits at only 330-435 kilometers above the Earth, isn’t even worthy of its name.

The international record-keeping body FAI (Fédération aéronautique internationale) defines the Kármán line at an altitude of 100 kilometres (54 nautical miles; 62 miles; 330,000 feet) above mean sea level.
14 lis 2022 · The Kármán line is a boundary 62 miles (100 kilometers) above mean sea level that borders Earth's atmosphere and the beginning of space. However, defining exactly where space begins can be...

Atmospheres have no clearly delineated upper boundary: the density of atmospheric gas gradually decreases with distance from the object until it becomes indistinguishable from outer space. The Earth's atmospheric pressure drops to about 0.032 Pa at 100 kilometres (62 miles) of altitude, compared to 100,000 Pa for the International Union of Pure ...
27 lis 2023 · Experts have suggested the actual boundary between Earth and space lies anywhere from a mere 18.5 miles (30km) above the surface to more than a million miles (1.6 million km) away. However,...
20 gru 2018 · Technically, the International Space Station—which orbits at an average height of 240 miles—would not be in space if we defined “space” as the absence of an atmosphere.
