The distance around the Tropic of Capricorn is greater.
The distance between Samoa and the Tropic of Capricorn is approximately 1,700 kilometers (1,050 miles).
roughly 3239 miles
The equator is a longer imaginary line.
The distance between the Arctic Circle and the Tropic of Capricorn is approximately 6,215 miles (10,000 kilometers).
== == The perimeter of the equator is the greatest because the earth is a flattened sphere shape due to the influence of centrifugal force - a result of its rotation. The tropic of Cancer is slightly greater than the Tropic of Capricorn as there is a majority of continental land in the north. Land has a higher elevation than sea and to go around it you have to go to a higher elevation (radius) which means a greater perimeter. The north south distance is the least as it is a straight line.
the tropic of Cancer
The Tropic of Cancer is the parallel of roughly 23.5° north latitude. The Tropic of Capricorn is the parallel of roughly 23.5° south latitude. The angle between them has to be roughly 47°.
The distance at across southern Africa at the tropic of Capricorn is about 1,520 miles.
the equator
The line of latitude between the Tropic of Cancer and Tropic of Capricorn is the Equator. It is located at (0^\circ) latitude and acts as the dividing line between the Northern and Southern Hemispheres.
the tropic zone
90 degrees of latitude are between the tropic of Capricorn and the Arctic Circle.
