Close encounters between these two planets are quite rare, occurring approximately once every 20 years, but this approach
exceptionally rare due to how close they will be to each other. Previously, this happened only on March 4, 1226. Patrick Hartigan, astronomer at Rice University
Jupiter and Saturn are approaching to each other since the summer. From December 16 to December 25, they will be separated by a distance less than the diameter of the full moon.
Residents of the equator will have better conditions forobservations, but the phenomenon will be able to be observed by all people on Earth if the weather permits. The planets will appear in the western sky about an hour after sunset. The further north the observer is, the less time he will have before the planets drop below the horizon. However, Jupiter and Saturn are bright enough to be seen at dusk.
The next time these celestial bodies will come so close is only on March 15, 2080, and after that only in 2400.
