Argh...my apologies for misunderstanding you, RN.
Well, the central point I was trying to make was that Mars' rotation period does not seem to be an artifact of primordial major impacts, although I'm sure that some such events certainly had an influence. Venus' case is entirely different...and just to throw a bit more churn into the mix, what in blazes must've happened to Uranus??? I am willing to accept chaotic early System events like major collisions as likely explanations for some current dynamic oddities like the Venusian rotation period & direction. However, Sagan's Law must still apply: extraordinary theories require extraordinary evidence. Using this heuristic, the "two-moon Venus" (or even one-moon) scenario seems difficult to defend. (Did someone just mutter "Hyperion"??? Quiet, you! ) -------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

what in blazes must've happened to Uranus??? This is solidly off-Venus-topic, but I was wondering recently: What if Uranus once orbited in the plane of its rotation and the tugs of other giant planets pulled it towards the ecliptic while the axis remained gyroscopically (near) fixed? |
