474-winter-solstice-diagram-dixon – The beginning of winter marks the time when earth, in its orbit, is oriented so that the northern hemisphere is maximally tilted away from the sun. This results in a shorter period of daylight and lower angle of incidence of sunlight; days are cool and short. Around the solstice, the sun does not rise as seen from any point north of the Arctic Circle. The Southern Hemisphere begins its summer at this time. Digital diagram © 2007 by Don Dixon.
