Venus' stormy atmosphere acts like a brake ... The gravity of the larger body keeps the rotational period of the smaller body in sync with its orbit around the larger body. That means the smaller ...

Venus is often called Earth's "Sister Planet ... less than 3° compared to Earth's 23.5° – and its very slow rotational period (the planet takes around 243 days to complete a single rotation ...

Venus isn’t so simple ... In research published in 2012, they showed that the average rotation period between 1991 and 2007 was shorter than the average rotation period measured by Magellan ...

If Venus was once as watery as Earth ... In the most extreme cases, that tidal force could have slowed down the rotational period by as much as 72 Earth days per million years.

Using these parameters we find that such a world could have had moderate temperatures if Venus had a rotation period slower than about 16 Earth days, despite an incident solar flux 46-70% higher ...

ACCORDING to my observations, this planet seems to have a very slow rotation, round an axis almost perpendicular to the plane of the orbit. Thus, a dusky spot remained fixed with regard to the ...

Whether the rotation axis of Venus did switch in the past depends upon its initial rotation period, according to Correia and Laskar. Their simulations suggest that the axis would only have flipped if ...

UCLA researchers may have discovered the cause of a huge, bow-shaped wave on Venus that has puzzled ... shortening its rotation period by about two minutes each day. The researchers reported ...
