2020, December 8-14: Jupiter begins its final approach to Saturn as a prelude to the Great Conjunction on December 21, 2020.
Jupiter and Saturn are found in the southwest after sunset. Begin looking as night falls, about 45 minutes after sunset. Jupiter is the bright star, about one-fourth of the way up in the sky above the southwest horizon. The observing window is good for about the next 90 minutes, but Jupiter gets lower in the sky. The pair sets about 3 hours after sunset.
Saturn is dimmer than Jupiter, but brighter than the other stars in region. The Ringed Wonder is to the upper left of the Jovian Giant.
During the week, Jupiter nearly cuts the gap to Saturn in half, from 1.1° to 0.7°
