Hello T0 th3 M4X.
Pretty sure Venus' rotational quirk wasn't known till radar equipped probes got into an orbit and started mapping said planet's surface.
As for a hypothetical cause? A more catastrophic, early accretion phase impact than the similar event that formed Earth's Moon in our planets distant paet/formative phase?
Now Neptune? I vaguely remember reading about the possibility of the larger planets 'Migrating' as they finished forming and stabilized their orbits. The finer details elude me at present and under current circumstances.
Also... I would say your bullet spin analogy is some what poor and that ice skaters... (Or perhaps roller skaters on a giant rubber surface ?) would be better?
Cheers!
Thank you. I'm pretty much in agreement with what you said. And not to nitpick, but the other planet is Uranus (just to clarify).
No issues on your statements on their potential migration. This was along the lines of what I was looking for from someone rather than just saying "randomness."
The bullet analogy may not be perfect, but I dunno about roller skaters on a giant rubber surface. There's probably a good analogy somewhere in between, but for the sake of the argument, I think your idea is "fair." When I said "bullets", I'm thinking about the kinetic energy that would've had to have been exerted to get that planet in its current orbit regardless of rotation, but I'll admit that the behavior that follows would probably be closer to a bad day at the roller rink.
Anyway, thanks for your thoughts. Much appreciated.
