December Solstice 2023: All About First Day Of Astronomical Winter In Northern Hemisphere, And Year's Longest Night

<p><strong>December Solstice 2023:</strong><span style="font-weight: 400;"> This year, the December Solstice, also known as Winter Solstice, falls in India on December 22, 2023. For some regions, it falls on December 21. The first day of astronomical spring in the Northern Hemisphere, the Winter Solstice can fall anytime from December 20 to 21. In rare cases, the winter solstice can fall on December 23. The last time the Winter Solstice fell on December 23 was in 1903. Winter Solstice 2023 falls at around 8:57 am IST on December 22.&nbsp;</span></p> <p><span style="font-weight: 400;">Winter Solstice is also the shortest day and longest night of the year in the Northern Hemisphere, and the longest day and shortest night of the year in the Southern Hemisphere. During the winter solstice, the Northern Hemisphere receives indirect sunlight, and the day is shorter than 12 hours, while the Southern Hemisphere receives direct sunlight. It is the beginning of&nbsp; summer in the Southern Hemisphere.&nbsp;</span></p> <p><span style="font-weight: 400;">The Northern Hemisphere experiences cooler temperatures, while the Southern Hemisphere experiences warmer temperatures.&nbsp;</span></p> <p><span style="font-weight: 400;">During the December Solstice, the Sun is exactly overhead the Tropic of Capricorn in the Southern Hemisphere. This is the southernmost latitude. So, for the Northern Hemisphere, the Sun is located farthest south. The Earth's North pole is facing away from the Sun.&nbsp;</span></p> <p><span style="font-weight: 400;">The word solstice is derived from the Latin word 'solstitium', which means 'the Sun stands still'.&nbsp;</span></p> <p><strong>MUST READ | <a title="NASA Features Orange Tabby Cat In First Video Sent From Deep Space To Earth Via Laser.

As a result, after the Winter Solstice, the days start becoming longer, and the nights shorter in the Northern Hemisphere. This will continue until the spring equinox in the Northern Hemisphere, and autumn equinox in the Southern Hemisphere.&nbsp;</span></p> <p><span style="font-weight: 400;">Earth is closest to the Sun during winter in the Northern Hemisphere, but the tilt of 23.4 degrees in the Earth's axis causes the Northern and Southern Hemispheres to receive different amounts of sunlight, resulting in different seasons.&nbsp;</span></p> <p><span style="font-weight: 400;">A few weeks after the Winter Solstice, Earth reaches perihelion, the point in the planet's orbit closest to the Sun.&nbsp;</span></p> <p><span style="font-weight: 400;">While the December Solstice marks the shortest day of the year in the Northern Hemisphere, and the longest day of the year in the Southern Hemisphere, the earliest sunset in the former and the earliest sunrise in the latter occur a few days before the December Solstice. This is because the true solar noon, which is the point at which the Sun reaches the highest point in one's sky, comes about 10 minutes earlier by the clock than it does at the solstice.&nbsp;</span></p> <p><span style="font-weight: 400;">It is due to the discrepancy between solar time and clock time that the earliest sunset and earliest sunrise are experienced ahead of the December Solstice, in the Northern and Southern Hemispheres, respectively.</span></p> <p><span style="font-weight: 400;">Another reason behind the discrepancy is the oblong orbit of Earth around the Sun. Since the rate at which Earth orbits the Sun depends on the distance between the two celestial bodies, and the Earth is located closest to the Sun around the time of the December Solstice, the planet spins faster, resulting in a larger difference between the solar time and closer time, than other times of the year.</span></p> <div class="article-data _thumbBrk uk-text-break"> <p><strong>MUST READ |<a title=" How Reindeer See Their Food In Dark Arctic Winters" href="https://ift.tt/XY5GHw0" target="_self">&nbsp;How Reindeer See Their Food In Dark Arctic Winters</a></strong></p> </div>
