What website can I find information about the annual cycle of the Sun?
Apologies. I have trouble with your question. The sun sits at the centre of our solar system. Planets which are elliptical in shape follow elliptical paths while orbiting the sun. Each of these orbits takes one planetary ‘year’ for a cycle to be completed. I am sure our entire solar system orbits some other entity out in space and in so doing one of those orbits when completed would be what we would describe as a ‘solar’ year. A ‘solar’ year would be one very long period of time and I do not know of any website that would cover that topic.
