In the rare astronomical phenomena, Jupiter and Saturn are going to reunite after 800 years. Today, December 21 will be the shortest day of the year 2020, while the night will be the longest night of the year. The world will be witnessing the rejoining of two largest planets of the solar system. This occurrence happened 800 years before in 1226 when these two planets were close to each other. This rare astronomical phenomenon can be seen on Monday in Jantar Mantar of Ujjain. It is called Winter Solstice. Due to this astronomical event, on 21 and 22 December, the day will be of 10:41 hours and the night will be of 13:19 hours.
A very few people are able to witness this astronomical event in their lifetime. So, for those who are living it will be great to see the conjunction of both planets. According to the US space agency NASA, both planets can be seen very close to each other in the evening. At the time of this event, the distance of Jupiter from the Earth will be about 5.924 Astronomical units and the distance of Saturn will be 10.825 Astronomical units. The two planets will certainly look close to each other, but the distance between them will actually be more than 73 million km (733860864 km) from each other.
Why December 21 is the Shortest Day?
According to scientists, the Sun enters from north towards south from the Tropic of Cancer to the Tropic of Cancer on 21 December. Because of which the rays of the sun remain on the earth for a very short time. During this time, the presence of the sun lasts for about 8 hours and after it sets up, it stays for about 16 hours.

TOMORROW Jupiter and Saturn will be at their closest separation in the sky since 1623 at 0.1° apart. Here's an animation showing exactly how close that is relative to a familiar object, the Moon! (Moon ONLY added to illustrate the scale) #GreatConjunction2020 pic.twitter.com/2mvdl6KjmI
