A great conjunction is a conjunction of the planets Jupiter and Saturn. Great conjunctions occur regularly (every 19.6 years, on average) due to the combined effect of Jupiter's about 11.86-year orbital period and Saturn's 29.5-year orbital period. The last great conjunction happened on 21 December 2020. It was the closest great conjunction since 1623.[1]
