This last happened in 2000, so it’s worth staying up for on this shortest day of the year. And, while you’re awake, look out for meteors! The Ursids shower will be in full effect.
This rare conjunction of these two planets is known as a “great conjunction”. (Didn’t we hear about those in the film “The Dark Crystal”?)
The two bright planets will appear only 7 arc minutes of each other in the night sky. They will be so close that they will appear to make a bright double planet. Look to the west just after sunset for this impressive and rare planetary pair.
