One interesting consequence of the varying offset between mean noon and solar noon is that the when the days get longer / shorter around the shortest / longest day, the change in the morning isn't always the same as the change in the evening. In the southern UK, where I live, sunrise might continue to get later for a couple of weeks while sunset gets earlier. It took me ages to understand why.
- enriquto 5y agoNow, can you prove that the shortest night of the year is adjacent to the longest day? This is indeed the case for all latitudes, but it is wickedly difficult to prove. Hint: start by setting up an imaginary planet with irregular orbit where this is not the case. Then find what property of the orbit you needed to force that does not happen with the earth.
