Orbital poles are the two regions of a planet at the extremes of its rotational axis.

Geographical poles are the two regions of a planet at the extremes of its rotational axis. The polar regions tend to be the coldest parts of a planet, which often receive the least light and heat from a star. A planet can also have magnetic poles: on Earth these are close to, but not quite the same as, the geographical pole.
