Question 21
(21) Last December 21, 2020, a very rare phenomenon was observed in the sky just above the southwestern or western horizon after sunset. It was the moment when planets Jupiter and Saturn appear at their closest. It was also the first time the planets became so close since 1623. The event has been dubbed the "Christmas star," because some astronomers have theorized the “Star of Bethlehem” could have been a product of a close approach of Saturn and Jupiter.
