Zero equates to a perfectly circular orbit. In our solar system, Earth has an eccentricity of 0.02, while Pluto’s highly oval-shape orbit around the sun is considered 0.25.

The Earth's next ice age is expected to begin in about 11,000 years -- unless human-caused global warming disrupts natural cycles. Barker said that without the Industrial Revolution, assuming ...

Given this, Barker et al. estimate that – in the absence of rising anthropogenic greenhouse gasses – the next glacial period would likely begin within the next 11,000 years as Earth’s ...
