A massive interstellar object passing through our solar system during its formative years likely altered the orbits of planets into trajectories observed today, a new study says. Interactions with ...

The orbits of the planets around the Sun have been the source for many a scientific debate. Their current orbital properties are well understood but the planetary orbits have evolved and changed since ...

Star and planet formation has largely been considered separate, sequential processes. But in a new study, scientists at Southwest Research Institute (SwRI) have modeled a different scenario where ...

In the outer Solar System, far from the light and warmth of the Sun, things can get a little… hinky. There, clusters of rocks have been orbiting in weird loops that some astronomers have attributed to ...

Since the formation of the Solar System, the orbits of the planets have evolved and changed over time. While one of the most prominent ideas in the last few decades is planetary migrations and the ...
