The period of rotation for Venus is 243 days. In other words, Venus takes 243 days to turn once on its axis so that the stars are in the same position in the sky. That seems like a long time, and it is. Especially when you consider that a year on Venus only lasts 224.7 days. I...
A revised period of rotation of Venus of 243.023 ± 0.002 d aligns the two data sets. This period of rotation agrees with pre-Magellan estimates but is significantly different from the commonly accepted value of 243.0185 ± 0.0001 d estimated from Magellan radar images. It is possible that ...
and is completely shrouded by dense cloud. The atmosphere is principally carbon dioxide. Mean distance from sun: 108 million km; period of revolution around sun: 225 days; period of axial rotation: 244.3 days (retrograde motion); diameter and mass: 96.5 and 81.5 per cent that of earth respec...

which rotate on their axes in an counter-clockwise direction, Venus rotates clockwise (called “retrograde” rotation). It also rotates very slowly, taking 243.025Earth days to complete a single rotation. This is not only the slowest rotation period of any planet, it also means that a single ...
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 terminator for three or four hours on the same dates, as well as on the following days. The ...
CARPENTER 1 noted in 1966 that the radar observations of the rotation period of Venus gave a figure remarkably close to one at which Venus would present the same aspect to the Earth at each inferior conjunction. Goldreich and Peale 2 discussed this as a possible resonance with a gravitational ...
timed wars and other important events based on their observations. In theDresden Codex, the Maya included an almanac showing Venus's full cycle, in five sets of 584 days each (approximately eight years), after which the patterns repeated (since Venus has a synodic period of 583.92 days)....
Studies also indicate that Venus rotates on its axis in a retrograde direction (opposite to the direction of revolution about the sun) with a period of about 243 days. Despite this slow rotation there is little observed temperature difference between the lighted and unlighted sides of the planet...
extensively about terraforming in the 1950s. In his 1954 novel,The Big Rain, Venus is altered through planetary engineering techniques over a very long period of time. The book was so influential that the term term “Big Rain” has since come to be synonymous with the terraforming of Venus....
