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...
When discussing Venus’ rotation, it is important to note certain distinctions. Rotation is the time it takes for a planet to spin once on its axis. This is different from a planet’s revolution, which is the time it takes for a planet to orbit around another object (i.e. the Sun). ...

changes, there’s many more people and we jump up and then again reach a limit, and we’ll talk about that as some Malthusian limit in this particular period, later we’ll discuss that, and then around here the industrial revolution happens and all of a sudden the population increases ...

The tower/beanstalk concept is entirely unworkable on Venus. It’s barely doable on Earth, and Venus simply doesn’t rotate fast enough (243 days per rotation) to hold an elevator or tower up. However, this has its benefits…sunrise to sunrise is about 117 days, and it would be quite...

This misalignment gives rise to a time-variable, but secularly negative (retrograde) torque acting on Venus. This torque brakes the initially prograde rotation of Venus. A symmetric couple torque is applied to Neith braking its retrograde orbital motion. Given enough time, this non-conservative ...
