Jupiter and Saturn came together in a ââ¬Ågreat conjunctionââ¬Â ââ¬â the nearest theyââ¬â¢ve been in nearly 800 years. Their closest moment occured on 12.21.20 at 1:21 p.m. ET. A conjunction occurs when two planets appear to meet each other in the sky, as seen from Earth. We can imagine the night sky like a clock, with Earth at the center, and each celestial body going along the clock face at its own pace depending on its orbit speed. Jupiter and Saturn meet every 20 years or so, but rarely do they get so intimate.
