THE BETHLEHEM STAR IS NOT A NATURAL OCCURRENCE
Some have remarked that the recent 2020 conjunction of planets could be the Bethlehem Star. It was not. The Bethlehem Star was not a normal occurrence. It was a unique, God-instituted, one-of-a kind event.
The Bethlehem Star was the star that led the Maji to Jesus. Mankind have known about conjunctions for centuries. They knew what stars were and what were conjunctions of planets. Since the Magi were called "Wise Men" in the Bible we must assume they in fact were wise. People of wisdom do not willy-nilly run off after natural known occurrences like planet conjunctions. They would note the conjunction but have no reason to see it as unusual. Therefore, the appearance of the Bethlehem Star must have been a truly out-of-the-ordinary event.
A Nova would have been much more unusual than a conjunction, it would have been a truly unique event and would have lasted much longer than a conjunction of planets. However, a nova would, like the stars, always stay in the same position in the sky; rising in the East and setting in the West each night for as long as it lasted. If you noticed where it set each morning over several days you would have traveled toward the West. Where would you stop? What is not far enough and what is too far? This type of travel would not have led you to a precise point, such as exactly to where Jesus was.
However, the Bethlehem Star would have to always be at the same compass bearing on the horizon to give an accurate line-of-travel. Moreover, as you neared Jesus' position the Star would appear to move to the zenith. When you reached Jesus the star would be exactly overhead. When it is so near the zenith to be confusing you would stop and ask for directions, which is what they did when they spoke to Herod. The Magi were men of great importance. We know because they came bearing expensive gifts: gold, frankincense, and myrrh. Because of their stature they could get directly in to see, Herod and Herod listened to them.
The Magi traveled a good distance from the East to where Jesus was. Being men of influence, they would have traveled with a large entourage: camels, servants, bodyguards, supplies for the trip and return. Moving so many people over a great distance would have taken a long time: weeks or months. Few people can afford such expense and time.
It would take a very unusual occurrence, like an exceptional direction-pointing star, not a nova or a conjunction, to cause these men to take such long, arduous trip.
