And now it's time for a little astronomy lesson. Remember, Astronomy and Astrology used to be the same thing until more recent years.
Earth has a north pole and a south pole, seasons, day and night, that sort of thing.
Uranus also has a north pole, but its pole point at the sun at all times. In other words, here's a planet that is about 90 degrees off from the rest of the solar system. This makes an excellent metaphor for a typical Aquarius. I call this the sign of the black leather jacket, but since so many kids these days are going for the biker look, an Aquarius won't actually wear a black leather jacket any more. But there's something decidedly unconventional about Aquarians.
