The woo-woos are anticipating judgement day. The rest of us can just marvel at this rare display by nature.
On 2020 DEC 21 at 18:21 UT Jupiter and Saturn will appear to have a geocentric angular separation of only 6.1 arcminutes, the narrowest since 1623 and until 2080. However, those separations are not small enough for Jupiter to occult Saturn. The last such occultation occurred in 6857 BC, while the next two will both occur during 7541.
Great Conjunctions between Jupiter and Saturn occur about every 20 years. That’s their mutual synodic (lapping) period with a mean value of 19.86 years. Sometimes the conjunctions are triple due to the effect of apparent retrograde motion, but not this time.
My Great Conjunction chart depicting the relative positions of Jupiter and Saturn during December 19-23 can be viewed at https://www.CurtRenz.com/jupiter.html
Photos and descriptions of the upcoming conjunction would be welcome additions to this thread.
