image of what it will probably look like in december
i read that on christmas, when it will be travelling away from us (it passes back and moves away from earth on christmas), it will remain above the horizon all night
STAR OF BETHLEHEM ???
but nov 28th it will be at closest to sun, and will probably be visible by day
