The names of which two points on the surface of the earth through which the axis of rotation of the earth passes?

The axis of rotation of the globe passes through the extreme southern and northern points of the planet, that is, through the North and South Poles. This axis is tilted with respect to the orbit of rotation, so half of the year the North Pole is directed towards the sun and there are warm seasons in the North Hemisphere, and the second half of the year the South Pole is on the sunny side, and there is summer, and winter begins in the north. And at the poles themselves, temperatures remain low throughout the year, since they receive very little heat from the sun.
