Earth's orbital eccentricity is 0.017; Mars' is 0.055, and Mercury's is 0.206. HD 20794d's orbit is more elongated than any planet in our solar system, with an eccentricity of 0.4. Its 647-day-long ...

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.

J.J. Müdespacher Mexico City, Mexico Earth's orbit around the Sun is not circular, but an ellipse that is slightly elongated with an eccentricity of 0.017. (An eccentricity of 0 is a circle ...

The chances of an asteroid striking Earth within the next decade has doubled in a matter of weeks, according to NASA ...

Changes in Earth's orbit have helped pace climatic change for millennia. Scientists are now trying to understand whether - and how - these changes remodeled the landscapes our ancient ancestors ...

an orbit with low eccentricity), whilst some appear rather flattened (highly eccentric orbits). — What is a solstice? — What is an equinox? — How fast is Earth moving? The sun doesn't sit ...

Simpson found that the inner planets experienced high obliquity and high eccentricity, leading to dangerous temperature differences between seasons. The mass may have even pushed Earth's orbit ...

These sapropel layers are packaged into groups of 4–5 (Figure 4), reflecting the influence of slight changes in the shape of the Earth's orbit around the sun (eccentricity) on modulating the ...
