The Earth is not a perfect sphere, but an oblate spheroid, meaning it bulges at the equator due to its rotation. The Kármán line, established at 100 kilometers above sea level, is widely recognized as the edge of space.
Understanding Earth's Equatorial Bulge and Polar Flattening
Defining the "Height" of the Planet The most common reference point for the height of Earth is the average sea level, known as the geoid. Tectonic and Geological Influences More perspective on Height of earth can make the topic easier to follow by connecting earlier points with a few simple takeaways.
The contrast between these two points illustrates the remarkable topographical variance of the planet, spanning nearly 20 vertical kilometers. The Highest Points and Lowest Depths The true range of Earth's vertical dimensions is revealed when examining its extreme elevations.
Understanding Earth's Equatorial Bulge and Polar Flattening
This results in an equatorial diameter that is about 43 kilometers larger than the polar diameter. This is the altitude where conventional aircraft wings no longer generate sufficient lift and orbital mechanics take over.
