My Bible says “star”, not two planets
The “star” of Bethlehem wasn’t a spectacular celestial event that was clearly visible to everyone. Otherwise, King Herod wouldn’t have needed to ask the chief priests and scholars when it appeared in the sky. He would have seen it himself.
Of course, the word star in those days also referred to the visible planets. They were wandering stars (mainly Jupiter, Saturn, and Mars) or morning and evening stars (mainly Venus and Mercury).
The Greek word Astera could apply to a Star or a constellation of stars. Astera Planetae referred to wandering stars.
A discussion.

For the interested there are a series of pictures that show a series of conjunctions that happened in 7-6 BC (Before Christ). The Magi, the astronomers of the time, took note of conjunctions that happened in and around the constellation Pisces. Pisces—a constellation of 2 fish—was associates with the Jews. Cut to the chase version is that the Magi saw a number of conjunctions occurring in Pisces in a way that suggested the birth of a King to the Jews and they came looking for him. A series of illustrations showing the conjunctions.

The same Greek word would apply to planets. It literally means heavenly bodies.
