Planetary conjunction

The sky was magnificent on Tuesday, maybe the best ever. Venus was west of the Moon and then Jupiter and Mars were on a clear arc through.
The conjunction has also included Saturn, Uranus and Neptune but just the three planets together was spectacular and too vast for my camera. All are on the same side of the Sun as us at the same time. I need to think some more about how to work out the next time it will happen from first principles.
