Planetary conjunction

 

I'm pretty slow on the uptake with some ideas. Whilst we were in Kent, I was sure that Venus and Jupiter had swapped places overnight. Turns out they had. Thinking about it, they are on the same plane as seen from Earth but Venus is moving faster across the sky, so at some point it will catch up and pass Jupiter, as seen from Earth. So at some point, they must occupy the same point in the sky. From deep in my memory, I dredged up the phrase "planetary conjunction". Turns out it is the correct term. And there was a conjunction of Venus and Mars in the early morning, 12 hours before I took this photo. See here.
