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

A day on Venus is unlike a day on Earth, which sees one sunset and one sunrise roughly every 24 hours. On Venus, the sun rises every 117 Earth days – or just two times per Venus year.

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 lower of the two sits below 70 kilometers (43.5 miles) in altitude, where the equivalent of hurricane-force winds on Earth blow against the direction of Venus' rotation.

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 ...

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 ...
