NO STAR !
A couple of bright planets will be close enough to appear as one star
Well yes we all know that, happy now.
They wouldn’t have known that back then. I don’t think planets were known and understood at that time. It is just one of the theoretical possibilities of the day.
I personally don’t think it was even a star, because this alignment will only last a couple of days and wouldn’t have lasted long enough for three Persian gentleman to make the trip to Bethlehem.
