The Tropic of Capricorn doesn't run in a direction, it's a circle around the Earth.

Here's how to think about it:

* Imaginary Line: The Tropic of Capricorn is an imaginary line that circles the Earth. It marks the southernmost point where the sun can be directly overhead at noon (during the December solstice).

* Latitude: The Tropic of Capricorn lies at approximately 23.5 degrees south latitude.

* Around the Globe: It runs completely around the globe, passing through countries in South America, Africa, Oceania, and Asia.

So, instead of "direction", we can say it runs east to west or west to east depending on your starting point.
