All of the above, depending on when you catch it. The axis points in a (roughly) fixed direction in space as the planet goes around the sun. At the moment Uranus's south pole points roughly at the sun; half an orbit later, the north pole will point at the sun. -- Henry Spencer @ U of Toronto Zoology {allegra,ihnp4,linus,decvax}!utzoo!henry
