Schematic illustration on how the super-rotation of Venus' atmosphere is maintained. In the cloud layer of Venus, a vertical and north-south circulation, called the meridional circulation ...

The pressure under this heavy atmosphere creates friction with Venus' rocky surface and has likely slowed the planet's rotation over billions of years, Pepper said. A 2020 study published in the ...

more NASA missions to Venus would help clear up some of the unknowns. Scientists don't know the size of its core, how it got to its present, relatively slow rotation rate, how its magnetic field ...

Venus spins at a much slower rate than Earth. One complete rotation of Venus takes 243 Earth days. Imagine a school day that long… To make things stranger, a year on Venus lasts only 225 Earth days.

The pressure on Venus's surface is about 90 times that of Earth, equivalent to being deep in the ocean, making it inhospitable to most life forms. Venus is covered in clouds of sulfuric acid, which ...
