The night of Decmber 21 will be the longest night of 2020 because two of the biggest planets of the solar system- Jupiter and Saturn will form 'The Great Conjuction' in the sky tonight. December 21, also marks the winter solstice in the Northern Hemisphere. The two largest planets in our solar system, will nearly overlap to form a "double planet," an event that hasn't been visible since the Middle Ages. This phenomenon last took place in the year 1623 and the next time it will take place will be after 2080.
The distance between the planets will remain same but the angle of viewing it from Earth will be aligned. From the Earth, the two planets will be viewed only 0.1 degrees apart, says experts. As per Space.com report Jupiter and Saturn are in conjunction when they have the same right ascension or celestial longitude. This is what is referred to as a 'Great Conjunction', signifying the rarity of the union because unlike conjunctions with the other bright planets, these two don't get close as often. Despite appearing super close, Jupiter and Saturn will actually be more than 450 million miles (730 million km) apart. Earth, meanwhile, will be 550 million miles (890 million km) from Jupiter
