"On 12.21.2020 (the December solstice), Jupiter and Saturn will align so closely in the night sky that they'll create a radiant point of light some call the "Solstice Star," "Star of Bethlehem" or the "Christmas Star."

"Alignments between these two planets are rather rare, occurring once every 20 years or so, but this conjunction is exceptionally rare because of how close the planets will appear to be to one another," said Patrick Hartigan, an astronomer at Rice University. "You'd have to go all the way back to just before dawn on March 4, 1226, to see a closer alignment between these objects visible in the night sky."

The event, sometimes referred to as The Great Conjunction, occurs roughly every 19 to 20 years, but this is the closest the planets will line up in the night sky since the Middle Ages."
