Jupiter and Saturn great conjunction – 6′ Apart
After this December 21, 2020 conjunction, the two planets will appear to trade positions, as Jupiter overtakes Saturn. Jupiter will progress to the east and draw farther and farther away from Saturn throughout the decade of the 20s.
This is a once in 20 years great conjunction Both planets will fit in a 100x eyepiece field. Jupiter takes almost 12 years to circle the sun but Saturn takes 29.5 so Jupiter inevitably catches and laps the Ring World.
