Other latitudes of particular importance are the [tropic of Cancer]? (latitude 23o27' north), the [tropic of Capricorn]? (latitude 23o27' south), the [arctic circle]? (latitude 66o33' north) and the [antarctic circle]? (latitude 66o33' south). Only at latitudes between the tropics is it possible for the sun to be at the zenith?. Only north of the arctic circle or south of the antarctic circle is the [midnight sun]? possible. All locations of a given latitude are collectively referred to as a parallel, because they are coplanar, and all such plane?s are parallel? to the equator. Latitude more loosely determines tendencies in climate, aurora?, [prevailing wind]?s, and other physical characteristics of geographic locations.

One nautical mile is equivalent to one minute (1/60o) of latitude.
