What key characteristic differentiates the South Celestial Pole from the North Celestial Pole for navigation?

The South Celestial Pole lacks a convenient, bright marker like Polaris

While the celestial sphere appears to rotate around the South Celestial Pole just as it does the North Celestial Pole, the proximity of a brilliant star to that point differs significantly between hemispheres. Navigators in the Southern Hemisphere do not have a single, easily identifiable anchor star like Polaris to determine south. Instead, they must rely on patterns formed by other stars, such as the asterism known as the Southern Cross, to approximate the location of the South Celestial Pole. This absence of a convenient, bright marker makes celestial navigation slightly more complex in the south compared to the north where Polaris offers an immediate reference.
