Here's why:
* Polaris is the North Star: It's located very close to the celestial North Pole, which is directly above the Earth's geographic North Pole.
* Latitude and Polaris: The altitude of Polaris above the horizon is roughly equal to the observer's latitude.
* Tropic of Capricorn: The Tropic of Capricorn is located at 23.5 degrees south latitude.
Therefore, since the Tropic of Capricorn is 23.5 degrees south of the equator, Polaris will appear 23.5 degrees above the horizon for an observer at the Tropic of Capricorn.
Note: This is an approximation. Polaris is not perfectly aligned with the celestial North Pole, and there might be slight variations due to atmospheric conditions and observer's location within the Tropic of Capricorn.
