The Tropic of Cancer and Tropic of Capricorn represent the northernmost and southernmost locations where the sun may be seen directly overhead (midsummer and midwinter respectively). Note that the latitude of is equal to the axial tilt.
5°N is the Tropic of Cancer. It runs through Mexico, Egypt, Saudi Arabia, India and southern China. The Tropic of Capricorn is at 23.5°S and it runs through Chile, Southern Brazil, South Africa and Australia.
