Detailed explanation-1: -The Kármán line (or von Kármán line /vɒn ˈkɑːrmɑːn/) is an attempt to define a boundary between Earth’s atmosphere and outer space, and offers a specific definition set by the Fédération aéronautique internationale (FAI), an international record-keeping body for aeronautics.

Detailed explanation-2: -Notes: Kármán line is the most widely accepted boundary of space, which is 100km above mean sea level. But the United States uses 80km as the edge of space. It was named after aerospace veteran Theodore von Kármán. Recently, British businessman Richard Branson reached the edge of space, to promote space tourism.

Detailed explanation-3: -A new study argues that the boundary between Earth’s atmosphere and outer space-known as the Kármán line-is 20 kilometers, or about 20%, closer than scientists thought.

Detailed explanation-4: -Where does space begin? For purposes of spaceflight some would say at the Karman line, currently defined as an altitude of 100 kilometers (60 miles). Others might place a line 80 kilometers (50 miles) above Earth’s mean sea level.

Detailed explanation-5: -The Kármán line is an arbitrary boundary between the atmosphere and outer space, named after the Hungarian-American physicist and aerodynamic pioneer Theodore von Kármán. It is set as the 100-km (62 miles) altitude above the Earth’s mean sea level.
