garran | <cola> my very educated mother just served us eight

Last night on IRC we were talking about planetary mnemonics, and how because none of us actually uses them we don't need to worry about revising them. In my own case, I realized that instead of ever having actually rigorously learned the order, I just have among my accumulated knowledge of each individual planet some idea of its relative position, so that if I need the order I just reverse-engineer it from that.

This goes something like,

Mercury: Between Venus and the sun
Venus: Next to Earth in one direction
Earth: Earth!
Mars: Next to Earth in the other direction
(Asteroids: Between Mars and Jupiter, separating the little planets from the gas giants.)
Jupiter: Huge! Next to the asteroid belt
Saturn: Next after Jupiter
Uranus and Neptune: True love forever!
Pluto: Icy sentry, far frontier

I do have the bad habit of picturing the planets all in a nice, orderly line, when in fact of course they're scattered erratically about their various orbits and sometimes Pluto's is actually inside of Neptune's (though that's not a problem anymore), and who knows exactly where they are relative to one another at any given moment? Possibly Rachel's dad.

So, anyway:

Pluto: Icy sentry, far frontier

I always expected that, while I might one day need to give up thinking, "there are nine [local] planets", if I did it would be because I was revising it upward. Going back to eight is a little disorienting; like I was living not in my own future, but in the future as imagined by some early science fiction author whose then-plausible suppositions were made a little silly by later discoveries.
