As Jupiter and Saturn will rendezvous and form a single bright object in the sky just a few days before Christmas, the 2020 great conjunction is sometimes also called the “Christmas star.”
In fact, some scholars have theorized that the original Christmas star, also known as the Star of Bethlehem, might also have been a great conjunction. According to Christian lore, a bright light in the sky led the Three Wise Men to the location of Jesus's birth.
