Star of Bethlehem

Did the star reappear to lead the wise men to Bethlehem?
The wise men already knew that they will be heading to Bethlehem after King Herod told them to go to Bethlehem. The star reappeared to lead them to and stand “over” (Matthew 2:9) the precise house in Bethlehem where Jesus was.

Had the star been leading them toward Bethlehem for two years?
If so, they wouldn’t have been “overwhelmed with joy” (Matthew 2:10) about the star continuing to go “in front of them” (Matthew 2:9). The fact that they were overwhelmed with joy to see the star again makes it more likely that they hadn’t seen the star for a long time, possibly since they first saw it in the east some two years prior.

What exactly was this star that “came and stood over where the young child was” (Matthew 2:10)?
The smallest star discovered to date is the red dwarf star code named EBLM J0555-57Ab, whose temperature is 3,500 degrees Celsius (6,300 degrees Fahrenheit) and whose diameter is 118,000 kilometers (73,000 miles). What hovered over a house in Bethlehem obviously wasn’t a fireball of nuclear fusion almost ten times wider than the earth, whose diameter is only 12,743 kilometers (7,918 miles).

Then what was the star of Bethlehem?
People back then didn’t know about nuclear fusion. To them, a star was simply a bright light in the night sky, so this star was a bright light in the sky that was small, close and cool enough to pinpoint Jesus’ house without burning anyone.

What other evidence is there that this “star” wasn’t a typical star?
Stars do not move across our sky once per night. They seem to do so, and always from east to west, because the earth rotates around its more or less vertical axis once every 24 hours. For a star to appear to move from north to south across our sky (Bethlehem of Judea is almost directly south of Jerusalem), the earth would have had to rotate around a horizontal axis.

How can the Creator of the universe make what appears to be a star move across the sky from north to south and use such a star to tell the wise men that the King of the Jews had been born?
 

Who should have accompanied the wise men to Bethlehem?
“All the chief priests and scribes of the people” (Matthew 2:4) who told Herod that the Messiah will be born in Bethlehem (see Bethlehem of Judea) and who knew that the wise men had said, “Where is the One who has been born King of the Jews? For we saw His star in the east and have come to worship Him” (Matthew 2:2). Upon hearing that their long-awaited Messiah has been born in Bethlehem and that foreigners are going there to worship Him, the Jewish religious leaders stayed home: “He came to His own, and His own did not receive Him. But as many as received Him, to them He gave the right to become children of God, to those believing in His name: who were born, not of blood nor of the will of the flesh nor of the will of man, but of God.” (John 1:11-13)
