The equator
That would be the equator, at zero latitude.
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 Tropics of Cancer and Capricorn are separated in latitude by roughly 47 degrees. You're free to draw as many or as few lines in that interval as would please you. Since they're drawn at equal latitudes north and south, the average of their latitudes is zero, and the imaginary line that represents their average latitude is the equator.
All of them do that have latitudes greater than -23.5
