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 ...

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 ...

Astronomers have discovered asteroid 2025 PN7, a tiny 'quasi-moon' that has been shadowing Earth in near-synchronised orbit for six decades and is expected to remain alongside our planet until around ...

Illustration of the uncertainty of Earth's orbit 56 million years ago due to a potential past passage of the Sun-like star HD7977 2.8 million years ago. Each point's distance from the center ...

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 ...
