The winter solstice marks the shortest day and longest night of the year. In the Northern Hemisphere, it occurs when the sun is directly over the Tropic of Capricorn, which is located at 23.5Â° south of the equator and runs through Australia, Chile, southern Brazil, and northern South Africa.This year, the Northern Hemisphere solstice will occur at 9:49 pm MST on December 21, 2015.herefore, on the day of the summer solstice, the sun appears at its highest elevation with a noontime position that changes very little for several days before and after the summer solstice. In fact, the word solstice comes from Latin solstitium or sol (the sun) + - stit-, -stes (standing).
This occurs on the June solstice, when the Northern Hemisphere is tilted toward the Sun to its maximum extent. Its Southern Hemisphere counterpart, marking the most southerly position at which the Sun can be directly overhead, is the Tropic of Capricorn. These tropics are two of the five major circles of latitude that mark maps of the Earth, besides the Arctic and Antarctic Circles and the Equator.
