-- The 'pole star', Polaris, is always nearly stationary in the sky.
-- It's located almost straight overhead when seen from the north pole.
-- When viewed from the equator, Polaris is right on the northern horizon.
-- Looking from anywhere in the southern hemisphere (south of the equator), Polaris is below the horizon, and can't be seen at all.
A person who was born and raised in the southern hemisphere, and who has never crossed the equator, has never seen Polaris, the "North Star" !
