Despite their overall similarities, asteroids are usually pretty distinct from one another. Vesta has a very different ...

Natural cycles in Earth's rotational axis and its orbit around the sun drive climatic changes, and now researchers have ...

Earth's last ice age ended around 11,700 years ago and a new study predicts the next one should be 10,000 years away. But the researchers say record rates of fossil fuel burning that are increasing ...

Could a giant planet between Mars and Jupiter have doomed Earth? A new study suggests that small changes would have been ...

and eccentricity on the rhythmic advance and retreat of ice sheets. A major challenge in determining the precise influence of orbital variations on glacial cycles lies in the striking similarity ...

The team compared the changes in orbital parameters to the glacial periods over the last 900,000 years. Eccentricity varies over 100,000-year cycles (and a second one over 400,000 years).

It features an orbital period of 18.94 hours and an eccentricity of 0.54. The pulsar's mass is under 1.6 solar masses, with a companion mass of at least 0.07 solar masses, suggesting a total ...

In the future, northern hemisphere summer will take place when Earth is closer to the sun, as Earth's orbital elongation, or eccentricity, varies. The Milankovitch cycles are all caused by the ...

Studying young gas giant exoplanets' compositions and orbits could help us better understand how our own solar system's gas ...
