What is the most northern place on Earth?

The most northern place on Earth is the North Pole.

More precisely, this is the Geographic North Pole, the point at 90° north latitude where Earth’s axis of rotation meets its surface. It lies in the Arctic Ocean, rather than on a continent, and is covered by drifting sea ice rather than permanent land.

The North Pole is different from the Magnetic North Pole. The geographic pole is defined by Earth’s rotation and remains the northernmost point by definition, while the magnetic pole is determined by Earth’s magnetic field and shifts over time. At the Geographic North Pole, every direction away from the point is south, and all lines of longitude meet there. The Sun also behaves unusually: it rises roughly once a year and remains above the horizon for about six months before setting for the polar night.
