Could the Southern Cross stand at the zenith at the South Pole? Is he the “polar star of the Antarctic countries”?

1) Could the Southern Cross stand at the zenith at the South Pole?
2) Is he the “polar star of the Antarctic countries”?
3) If not, what latitude was the Nautilus at?

1) No.
2) No. The Southern Cross is not a star, but a constellation that occupies a position in the sky from 55њ to 64њ S declination. The south pole of the world lies in the constellation Octantus, near the sigma star Octantus. Here is the sigma Octant and is the South Pole Star.
