Q&A: Galactic Escape Velocity and More... Featuring Astronaut Terry Virts

Oh, also missed the biggest factor which is pertinent to the original question, no less: a backwards-spinning Earth would draw the Moon back toward itself rather than boosting it to a higher & higher orbit which is what's happening now. Also, our satellites would experience similar drag, but a more immediate effect would be that GEO sats -- assuming they remain unaffected by the change itself -- would suddenly appear to orbit the Earth every 12 hrs, & LEO sats including the ISS would appear to scream once around every ~45 minutes. ^_^

W/regards to Venus' rotation, BLUF: we must not present as "Fact" that which is currently nothing more than popular opinion, especially when other opinions exist which are also supported by observation. 1) Venus is not the only planet (dwarf or otherwise) whose axis of rotation is tipped greater than 90 degrees relative to the plane of its orbit (Uranus = ~97.9; Pluto = ~122.5). 2) Rotating planets, like spinning tops, are not easily "flipped" due to gyroscopic forces, and such a flip in Venus' case would have to have been remarkably precise to a) nearly cancel the rotational energy of the planet while simultaneously b) almost exactly flipping the North pole with the South. Similar problems exist when ascribing an impact to the tilt of Uranus, e.g., as well (though these center around Uranus' family of satellites, a feature Venus lacks). 3) If axial tilt &/or counter-rotation are "proof" of impact(s) by planitesimal(s), then of all the planetary bodies in the Solar System only Mercury (w/axial tilt of ~1 degree & 3/2 tidally locked rotation/orbital resonance) can be presumed to NOT have experienced at least one such impact. 4) Though it is the most commonly cited explanation for Venus' tilt, to date no other corroborating evidence for a planetary impact on Venus exists. 5) The phenomenon of the Venusian rotation DOES coincide with that explained by a gravitational resonance between the orbits of Earth, Venus & the Sun, though that point is also somewhat controversial & by no means certain at this time.
