Jupiter and Pluto 41′ apart – 3rd of a triple conjunction

13/11/2020

A triple conjunction is an astronomical event where two planets or a planet and a star meet each other three times in a short period, either in opposition or at the time of inferior conjunction, if an inferior planet is involved. The visible movement of the planet or the planets in the sky is therefore normally prograde at the first conjunction, retrograde at the second conjunction and again prograde at the third conjunction.

Jupiter and Saturn great conjunction – 6′ Apart

21/12/2020

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.
