The Great Conjunction
The Great Conjunction of Jupiter and Saturn
On December 21, Jupiter and Saturn will put up a spectacular display in the evening sky. They will be so close that they will appear to overlap completely, creating a rare “double planet” effect. This celestial synchronisation, also referred to as the “Christmas Star,” has not occurred in nearly 800 years. Last time they were so close together was on March 4, 1226.
Jupiter and Saturn will appear to the unaided eye as a single bright object low in the southwestern sky. The Great Conjunction can be seen from everywhere in the world.
