I found this very interesting short science video regarding a Conjunction of Planets Jupiter and Saturn... Here is the Description by The Cosmos News:
"Jupiter, Saturn to form closest ‘great conjunction’ in 800 years! On Dec. 21, 2020 the date of the December solstice, Jupiter, the largest planet in our solar system, and ringed Saturn, the second-largest, will line up perfectly to look like a double planet in the night sky.
The two planets will be so close that they will appear to be touching, separated by one-fifth the diameter of a full moon. It will be the closest they’ve appeared since March 4, 1226."
As one can see from the Posted Text, this is an event that has not occurred since 1226 A.D.
