If someone is determined to reject a coming Rapture of the body of Christ believers, any niggle will do.
The Star the Wisemen used was at least 2 or more years in position as Jesus was already moved out of the manger(being at least 2-3 years old) and into a “house”. Planets don’t stay in one position for any length of time and neither do star constellations. This Star stayed stubbornly over Jesus Christ until such time the wise men visited; they knew the behaviors of stellar objects so the behavior of this stellar object was so unusual they had to follow it. That is why Herod had the boys 2 years or younger killed in that region...because the stellar event was at least 2 years in duration before anyone in Judea had even noticed or had been apprised of its appearance; until the wise men told Herod about it.
So I would be careful about the whole popular notion of using planets and constellation movements to depict or to bolster the predictions of out of the ordinary historic events. The old wiseman or magi could already predict when and where alignments would occur; they knew the heavens were in motion. The heavenly body they were following showed no motion though the heavens were in motion all around it. The star still appeared through all seasons despite the fact that many stars and constellations don’t appear nightly throughout the year because the Earth has moved to a position where the sun’s light blocks the appearance of such stars or planets...or they have dipped lower below horizon (but then rise up over the Horizon to be seen again 6 months later).
But not the Star of Bethlehem....indeed it appeared to “go before them until they came upon the house where the star appeared above where the child was staying”. They had seen his star shining apparently motionless from where they were in the “East” but...Matthew 2:9”…9After they had heard the king, they went on their way, and the star they had seen in the east went ahead of them until it stood over the place where the Child was. 10When they saw the star, they rejoiced with great delight. “
This was an unusual star....we know it was in position for at least 2 years or more. It might have taken the Magi some time to note that it did not move with the seasons the way other stars and planets did(with the exception of Polaris...even the dipper stars move nightly and have differing positions with the change of the seasons). This star did not move nightly or with the seasons...it may have taken the magi months or more to realize what was happening but when they did, they realized something momentous was happening. So they had to investigate(the same way the Babylonians investigated when they realized that God had held back the turning of the sun 6 hours for King Hezekiah)
Yet it appears when they got to Jerusalem, no one seemed aware (showing what Jesus lamented about concerning those of Israel “who did not know the time of His coming”) of the Star and of it’s importance. Yet Herod quickly grasped a possible threat to his reign and enquired as to when the star had appeared. The priests told the Magi that their prophecies spoke of the Messiah being born in Bethlehem. So thus they went and saw the child and then went home another way not returning back (being warned of God).
Herod, thus had the boy babes in the Bethlehem region killed that were 2 years and younger....why? Because the star had been in singular position for 2 years according to the magi. Heavenly bodies are normally in motion...this one wasn’t! Only when the Magi were pointed in the direction of Bethlehem did the “star” seem to “go before them until it stood over the house where Jesus was”( Bethlehem was only about 5 miles away so the star would have been practically over head anyway...funny though...only these Magi seemed to be very aware of the unusualness of this star).
