Another fascinating twist has to do with Venus’ rotation. In his initial models of 2.9 billion year old Venus, Way stuck with a slow, modern-day rotational period of 243 Earth days.

The slow rotation period of Venus (it takes 243 Earth days to complete one full rotation) and the orientation of its spin axis to its orbital plane (177°, so it spins in the direction opposite ...

Simulations suggest that if ancient Venus had an ocean, tidal forces may have slowed the planet's rotation speed down to the point that the ocean evaporated ...

It was evident that in the case of Venus the rotation period was to be reckoned, not in hours, but in days. It being thus demonstrated what it was not, it remains now to determine what it was.

It was discovered that Venus' slow rotational period of 117 Earth days, in conjunction with the ancient analog of our Sun used in the study, combined to create a hospitable surface temperature ...

CAN the rotation period of Venus be commensurate with its synodic period? If the rotation period is 243.16 days retrograde, the axis of Venus which points toward the Earth at one inferior ...

Venus was already known for fast winds, but new research now finds that their speed has steadily been increasing over the last six years.

DURING the years 1876 and 1878 I paid some attention to Venus at the Kempshot Observatory, and although no distinct markings on the disc were seen in the very small equatorial, yet the following ...

The surface of Venus in false color (NASA/JPL) There are a lot of "ifs," though. The simulation depends on the rotational period and topography of Venus being about the same as they are today ...

Attempts to measure the exact rotation period of the planet, however, have been difficult. Different spacecraft have all come up with slightly different answers, on the order of a few minutes.

“Most initial conditions will drive the spin of Venus towards its present state, but through two very different evolutionary paths”, says Laskar. Whether the rotation axis of Venus did switch in the ...

Both new studies also detected regular variations in the atmosphere of Venus that appear to be linked to the rotational period of the planet, the local time of day and the height of the sun above ...
