If you look on a globe, in addition to the equator, you’ll see two other lines labeled tropics. These lines represent where on earth, as the planet shifts on its axis through the seasons, the sun is directly overhead at each solstice. Everything north or south of the tropics has noons at less than 90⁰ year round.
