Many historians have attempted to determine the date of Jesus' birth by looking for records concerning comets, meteors, supernovae, conjunctions of planets, and the like.
What was the "star" that led the wise men to Jesus Christ in Bethlehem? Was it a physical star at all? Whatever it was, the "star" (Greek aster) was definitely of miraculous origin; it was no ordinary, physical star. For instance, it had the ability to move. Matthew writes that the star "went before them, till it came and stood over where the young Child was" (Matthew 2:9). No star we have ever seen can do that! Even shooting stars—really meteors burning up in the atmosphere—cannot change directions and stop over a specific place!
"His star" (verse 2) was possibly—perhaps even probably—an angel. These spirit beings have a glorious appearance like a radiating star, and they can certainly move and change directions to show someone the way. Stars in the Bible often symbolize angels, for example:
» [Where were you] when the morning stars sang together, and all the sons of God shouted for joy? (Job 38:7)
» His tail drew a third of the stars of heaven. . . . And war broke out in heaven: Michael and his angels fought against the dragon; and the dragon and his angels fought. (Revelation 12:4, 7)
