In mathematics, a great circle or orthodrome is the circular intersection of a sphere and a plane passing through the sphere's center point. Any arc of a great circle is a geodesic of the sphere, so that great circles in spherical geometry are the natural analog of straight lines in Euclidean space. For any pair of distinct … See more To prove that the minor arc of a great circle is the shortest path connecting two points on the surface of a sphere, one can apply calculus of variations to it. Consider the class of all regular paths from a point See more Some examples of great circles on the celestial sphere include the celestial horizon, the celestial equator, and the ecliptic. … See more • Great Circle – from MathWorld Great Circle description, figures, and equations.
