The explanation of why December 21 is the shortest day of the year

A shocking astronomical phenomenon takes place every December 21. It is the winter solstice, which for the northern hemisphere of the Earth produces the shortest day of the year.

The solstice is known as the moment in which the sun reaches its greatest declination in latitude with respect to the equator. In accordance with National Geographicthe axis of the planet Earth has an approximate inclination of 23.4º that does not vary much during its journey, so it will always be inclined in the same direction, regardless of the position of the planet.

When the solstice occurs, one of the hemispheres receives a greater incidence of solar rays than the other. The Capricorn solstice, which begins summer, represents the longest day of the year in the southern hemisphere, while in the northern hemisphere it marks the beginning of winter and represents the longest night of the year.
