Karman line

The Karman Line is an internationally designated altitude commonly used to define outer space. According to definitions by the Fédération Aéronautique Internationale (FAI), the Karman or Kármán line lies at a height of 100 km (about 62 miles) above Earth's surface (ie. in technical terms 100 km above mean sea level). It was named after Theodore von Kármán.

Around this altitude the Earth's atmosphere becomes negligible for aeronautic purposes, and there is an abrupt increase in atmospheric temperature and interaction with solar radiation.
