Why is the equator closer to the sun?

Earth's surface is curved. Therefore, people living between the tropics will be closer to the sun by the difference of earth's radius to the latitude of those outside the tropics. The tropics are the Tropic of Cancer and the Tropic of Capricorn.

In other words, during the summer solstice of the nothern hemisphere those on the Tropic of Capricorn (at high noon) are actually slightly closer to the sun than even those living on the equator. Those on the equator are only closest to the sun (at high noon) during the equinoxes. Anyone on the southern pole near winter solstice will be the furthest possible distance from the sun humans can get on the surface of the earth--since earth currently approaches aphelion during the southern pole's winter solstice.
