The Sun will appear to be at its most southerly point about our planet today, wherever you are on the planet. This is because of Earth’s tilt, which causes our star to appear to rise and fall between the two tropics as the planet orbits the Sun. It will arrive at the Tropic of Capricorn today, December 21.
This event takes place at precisely 9:27 p.m. CST, 10:27 p.m. EST, or 3:27 a.m. UTC/GMT on December 22nd, tomorrow. This signifies the season’s astronomical change. It will be the start of winter in the Northern Hemisphere and the beginning of summer in the Southern Hemisphere. There will be less than seven hours of daylight in Edinburgh, the capital of Scotland, as the sun sets at 3:39 pm local time. It won’t get light again for several months at the North Pole, where it hasn’t seen one since October.
Translating the Latin word “solstice” as “the Sun is still” or “the Sun has stopped” Astronomers have compared the motion of the Sun to that of a ball thrown into the air, which appears to stop moving when it reaches its highest altitude and then begins again, because the Sun appears to reach either its highest or lowest point in the sky.
Over a full year, the Sun forms a unique figure-eight shape known as an analemma.
