Eccentricity of the Earth's orbit around the Sun. The fluctuation between a nearly circular and elliptical orbit drives cyclic changes in the Earth's environment, including the global carbon cycle.

Such an object with less than 0.25 eccentricity (a roughly circular orbit), therefore, would have an average altitude of 2,042 km (1,269 mi). The ISS is in a low Earth orbit. Credit: NASA Despite ...
