Which line of latitude is approximately 23 degrees South of the equator?

The Tropic of Capricorn is indeed located at approximately 23 degrees South of the equator. This line represents the southernmost latitude at which the sun can be directly overhead at noon during the December solstice. This phenomenon is a significant marker in understanding Earth's climates and seasonal changes, particularly in the Southern Hemisphere.

In contrast, the Tropic of Cancer is situated at approximately 23 degrees North of the equator and marks where the sun is directly overhead at noon during the June solstice. The equator itself is the zero degrees latitude line, while the Antarctic Circle is located much farther south, typically around 66.5 degrees South, making the Tropic of Capricorn the accurate answer for the line of latitude in question.
