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.

Earth’s orbit around the Sun is not circular, but an ellipse. The perimeter of Earth’s orbit is roughly 584 million miles ...

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.

the eccentricity of the earth's orbit, and even fluctuations in the amount of carbon dioxide in the atmosphere, have individually or collectively been invoked. The influence of ocean currents ...

A 128-minute orbit, according to Kepler's third law, works out to a semi-major axis of 8,413 km (5,228 mi). Such an object with less than 0.25 eccentricity (a roughly circular orbit), therefore ...
