Located less than 20 light years away, HD 20794d could potentially be one of the most Earth-like planets found so far, ...

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 discovery of a potentially habitable 'super-Earth' exoplanet, HD 20794 d, was published in the scientific journal ...

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 ...

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 ...

Solar radiation received at low-latitude is principally affected by variations in the cumulative effect of eccentricity ... Pliocene-Pleistocene. Earth and Planetary Science Letters 220, 3-24 ...
