What is Great conjunction?
A '''great conjunction''' is a [[conjunction (astronomy and astrology)|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.<ref>Jupiter-Saturn Conjunction Series from 0 to 3000 AD.
