Christmas Star
The two largest planets in our solar system are coming closer together then they have been since the Middle Ages and it is just happening in time for Christmas.
While it's not an actual star, the two planets will certainly make a bright splash in the night sky. On the night of December 21, the winter solstice, Jupiter and Saturn will appear so closely aligned in our sky that they will look like a double planet. This close approach is called a conjunction. You'd have to go all the way back to March 4, 1226, to see a closer alignment between these objects visible in the night sky.
