Schematic illustration showing the relative height of space compared to the overall size of the Earth. Space does not have a definitive, hard boundary. The atmosphere gradually thins until at a somewhat arbitrary point called the Karman line, space is considered to begin. This is at a height of just 100 km, indicated here by the blue line. The outer shell, marked by the red line, corresponds to an altitude of 400 km - roughly that of the International Space Station (ISS). Seen relative to the Earth's landmasses (here showing Europe), one can see just has tiny these heights are in the overall scheme. | |
