So the sun is changing it's distance from the surface of the earth as moves between the tropic of Capricorn and Cancer? Is the sun at the center of the dish?So what angle is the "dish" tilted at compared to the earth?
The tilt changes throughout the year, and I provided an illustration which shows what angles it tilts between. The apparent angles in the sky it moves between are listed in the left margin:
This "dish" is constantly tilting throughout the year, or rather wobbling, with the sun being a fixed location on that wobbling dish. This means that when the sun is low whatever is on the opposite side of the dish is high, and when the sun is high, whatever is on the opposite night side is low.
