Appulses of Jupiter and Saturn
Abstract
The latest conjunction of Jupiter and Saturn occurred at an optical distance of 6 arc minutes on 21 December 2020. We re-analysed all encounters of these two planets between -1000 and +3000 CE, as the extraordinary ones (<10) take place near the line of nodes every 400 years. An occultation of their discs did not and will not happen within the historical time span of 5,000 years around now. When viewed from Neptune though, there will be an occultation in 2046.
