When to Use Karman Line & Atmosphere Layers 3D Explorer

Reviewed by

Open the Karman Line & Atmosphere Layers 3D Explorer when you need to see which named layer a given altitude falls in, or compare the Karman line against the US boundary.


An altitude-layer and boundary lesson

A lesson starts when you drag the probe up through all four layers, then jump between the Karman line and the US boundary to see the roughly 20 km gap, and finally check the ISS orbit and the meteor and aurora zone.


Sessions this explorer does not fit

Sessions this page does not fit are comparisons of DIFFERENT PLANETS' atmospheres - use the Gas Giant Atmosphere Explorer for that - or a real-time sunlit and dark map of Earth - use the Earth 3D Globe. Walk the controls in the step-by-step guide.
