A super-Earth planet that dips in and out of its star's habitable zone has been discovered just 19.7 light-years away.

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 Earth’s orbit might feel like one of the most fundamental ... Kaib said: "It has already been proposed that Earth's orbital eccentricity was notably high during this event but our results ...

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 ...

Researchers have discovered an Earth-like planet with such an eccentric orbit that it swoops in and ... or "eccentric"—but HD 20794d's eccentricity is particularly elongated.

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 ...
