hideCoordinates: 45°0′0″N 0°0′0″E / 45°N 0°E / 45; 0
The Northern Hemisphere is the half of a planet that is north of the equator—the word hemisphere literally means 'half sphere'. It is also that half of the celestial sphere north of the celestial equator. Earth's northern hemisphere contains most of its land area and most of its human population (about 90%).
