If you haven’t seen Jupiter and Saturn, you’re missing something! | Astronomy Essentials | EarthSky

A *deep* dive into what’s happening RIGHT NOW. Look up more than one night. 

[snip] The 2020 great conjunction of Jupiter and Saturn will be the closest since 1623 and the closest observable since 1226! On December 21, Jupiter and Saturn will be only 0.1 degree apart. [“Then the two largest worlds in the Solar System will appear in Earth’s sky separated by only about 1/5 the apparent diameter of a Full Moon.”] Some say the pair will look like an “elongated star” on that date. Will they? Or will they look like a double planet? To know for sure, we’ll have to look and see. They’ll surely be an appealing and mind-expanding sight.

2002’s extra-close Jupiter-Saturn conjunction won’t be matched again until the Jupiter-Saturn conjunction of March 15, 2080.
