Great circle - Wikipedia
A great circle is the largest circle that can be drawn on any given sphere. Any diameter of any great circle coincides with a diameter of the sphere, and therefore every great circle is concentric with the sphere and shares the same radius .
Great Circle Mapper
Dec 23, 2024 · The Great Circle Mapper displays maps and computes distances along a geodesic path. It includes an extensive, searchable database of airports and other locations.
Great Circle Map
Great Circle Map displays the shortest route between airports and calculates the distance. It draws geodesic flight paths on top of Google maps, so you can create your own route map.
Why Are Great Circles the Shortest Flight Path?
Jul 5, 2019 · A great circle is a circle on the globe such that the plane passing through the sphere’s center is equal to the circumference of the Earth. Alternatively, a great circle is where the radius is equal to that of the globe representing the shortest distance between two points on the surface of the earth.
Great Circle Calculator
Oct 3, 2024 · The great circle is the closed circle deriving from the intersection of a sphere and a plane passing through the center of the sphere. The intersection traces the largest possible closed path on a sphere. This definition, of course, allows you to create infinitely many great circles.

Oct 19, 2023 · A great circle is the largest possible circle that can be drawn around a sphere. All spheres have great circles. If you cut a sphere at one of its great circles, you'd cut it exactly in half. A great circle has the same circumference, or outer boundary, and the …
Great Circle -- from Wolfram MathWorld
6 days ago · A great circle is a section of a sphere that contains a diameter of the sphere (Kern and Bland 1948, p. 87). Sections of the sphere that do not contain a diameter are called small circles. A great circle becomes a straight line in a gnomonic projection (Steinhaus 1999, pp. …
Great Circles—Definition and Examples in Geography - ThoughtCo
Jan 22, 2020 · A great circle is defined as any circle drawn on a globe (or another sphere) with a center that includes the center of the globe. Thus, a great circle divides the globe into two equal halves. Since they must follow the circumference of the Earth to divide it, great circles are about 40,000 kilometers (24,854 miles) in length along meridians.
Great circle - Simple English Wikipedia, the free encyclopedia
A great circle is the largest possible circle that can be drawn on a sphere, one that divides the surface into equal halves, called hemispheres. It is a circle that has the same diameter as the sphere it was drawn on.

Great circles are the “straight lines” of spherical geometry. This is a consequence of the properties of a sphere, in which the shortest distances on the surface are great circle routes. Such curves are said to be “intrinsically” straight.
