During the early days of our solar system, giant impacts were common occurrences. Earth likely experienced such an impact ...

The researchers found that Venus' simulated rotation speed had a profound impact on how the climate of paleo-Venus evolved over time. Currently, Venus spins extremely slowly, with a year that's ...

A Single Day on Venus Is Longer Than a Venusian Year Venus rotates around its axis extremely slowly.

Venus rotates very slowly, taking 243 Earth days to rotate once around its axis. Despite this very slow rotation, Venus’s atmosphere rotates westward 60 times faster than its planetary rotation.

The best models for how Venus’ atmosphere behaves and circulates, known as Global Circulation Models (GCMs), predict super-rotation to occur in much the same way on Venus’ night side as on its ...
