How Do the Clouds On Venus Move and How Long Do the Clouds On Venus Take To Rotate Around the Planet?

The clouds on Venus move, but not like clouds on Earth. Venus’s atmosphere is very thick and heavy.

There are no major temperature or air pressure changes to cause air currents, as on Earth, but Venus’s atmosphere rotates around the planet at a fairly steady rate of 225 miles (360 km) per hour.

The cloud cover, however, has never broken once in the history of Venusian studies.

Through telescopes fitted with ultraviolet filters, astronomers can make out certain dark patterns on the clouds.

By watching the dark spots, they have been able to clock the rotational speed of the clouds.

It takes 4 Earth days for Venus’s clouds to make one rotation around the planet.
