An illustration of Mimas’s ice shell evolution, in which the changes in ice shell thickness (y-axis) lag behind the eccentricity decay (inverted x-axis). Time increases to the right of the plot, while ...

Breakthrough discovery provides new clues about how these celestial bodies - that push the known laws of physics to their limits - find each other.

Professor John Chiang of UC Berkeley explains the impact of Earth's axial tilt and orbital eccentricity on global climate. He highlights their influence on seasonal variations, including monsoon ...

A passing star which blew past our solar system nearly 3 million years ago could have altered the Earth’s orbit, researchers found. The study, published last week in the journal The Astrophysical ...

This artist’s impression shows a Jupiter-like exoplanet that is on its way to becoming a hot Jupiter — a large, Jupiter-like exoplanet that orbits very close to its star. NOIRLab/NSF/AURA/J. da Silva ...

Breaking all previous records with an eccentricity of over 2.5, interstellar comet 3I/ATLAS is defying expectations and challenging established models of orbital mechanics. (A conceptual image of the ...

These two curves show the final distribution of orbit shapes for giant planets and brown dwarfs. The orbital eccentricity determines how elongated the ellipse is, with a value of 0.0 corresponding to ...
