And according to our primitive ancient ancestors, comets were omens of Doom, not of goodness, victory, success, and other sweet things. You cannot follow a meteor on horseback for five miles, it poofs long before that.
Star of Bethlehem in General:
Star of Bethlehem in King James version of the Bible:
Jerusalem <-Wise Men<- EAST
 Now when Jesus was born in Bethlehem of Judaea in the days of Herod the king, behold, there came wise men from the east to Jerusalem,
E King A of Jews' S Star T
 Saying, Where is he that is born King of the Jews? for we have seen his star in the east, and are come to worship him.
The answer given by the chief preists and scribes:
 When Herod the king had heard these things, he was troubled, and all Jerusalem with him.
 And when he had gathered all the chief preists and scribes
of the people together, he demanded of them where Christ should be born.
 And they said unto him, In Bethlehem of Judaea: for thus it is written by the prophet,
 And thou Bethlehem, in the land of Juda, art not the least among the princes of Juda: for out of thee shall come a Governor, that shall rule my people Israel.
 Then Herod, when he had privily called the wise men, inquired of them diligently what time the star appeared.
 And he sent them to Bethlehem, and said, Go and search diligently
for the young child; and when ye have found him, bring
me word again, that I may come and worship him also.
 When they had heard the king, they departed; and, lo, the star, which they saw
in the east, went before them, till
it came and stood over where the young child was.
Result: It no longer went before them when it both came and stood over where the young child was.
The Question Raised: When did they no longer see it in the east?
Answer: When they looked away, only to see it later in the south.
Result: They saw it in the east until it came and stood over where the young child was.
The Question Raised: How can this be true if the "star" was seen in the southern sky?
Answer: It's not true that the star was in the east during the journey, so this interpretation must be wrong.
Two types of "above"
.J M e A s G u I s. Something else
Result: The star is directly above Bethlehem when the Magi are close by.
The Question Raised: Is this "star" at the zenith?
Answer: A star that was in the east could, at the Middle East Latitudes, be located at the Zenith. A two hour journey would be consistent with a celestial sphere rotation of (2/24)*360 degrees or 30 degrees, which is about three times the width of a fist held along the celestial equator. The east from "two hours ago" must have been very insignificant if a star (a real one to put it midly) would have been directly above when the Magi were at Bethlehem. With horse travel the stars would have little chance not to travel less than 30 degrees in the sky, making the "eastwardness" of the "star" at the beginning of journey even less significant. Would you try to follow a star that is right above you head for over 5 miles? (fyi. exactly following a star will render a curved, indirect path)
Result: Bethlehem seen from a distance is seen under the location of the star in the celestial sphere.
Question: From what perspective and distance is this acceptable?
Answer: From the north, looking in a southernly direction from a sufficiently large distance from Bethlehem, but not within Bethlehem itself. At Bethlehem, the "star" is seen "above" something else that may be 5 miles to the south!
The (so said) "star" had perspective aboveness with respect to Bethlehem during most of the journey, and physical aboveness over Bethlehem during the end of journey. Going "before" the 3 Wise Men, was the (so said) "star", which is consistent with a mobile "leader" which the Wise Men followed in the same direction that the (so said) "star" travelled.
Is the diagram above correct? If yes or no, where is the "star" at this point? If you said no, and if you believe the star is at the zenith with respect to Bethlehem (5 miles from Jerusalem), then explain how you believe that the three wise men followed this star. If you said yes, then why by the time the 3 Wise Men reach Bethlehem is the star "over" a place 5 miles to the south, for because of this the star is no longer "above" Bethlehem for people at Bethlehem! If you said no, and answered that the so-called "star" was moving at a pace similiar to the 3 Wise Men's mode of travel, but somewhere above and front of them, then you understand where I'm coming from.
 When they saw the star, they rejoiced with exceeding great joy.
 And when they were come into the house, they saw the young child with Mary his mother, and fell down, and worshipped him: and when they had opened their treasures, they presented unto him gifts; gold, and frankincense, and myrrh.
- Not all "wise men" (magi) are "astrologers". That should be obvious.
- Primitives did not need a "special star" or planetary alignment to navigate their way from Jerusalem to Bethlehem.
