I just learned the sun has an equatorial rotation rate of approximately 25 earth days, and a polar rotation of approximately 31 days. Intuitively, by the laws of physics, it should be the other way around: longer at the equator and shorter at the poles? Also, if our solar system is within a larger orbit, is there a year for the sun in that orbit? What I read is in terms of our year here on Earth - not that there is anything wrong with the Earth year, of course. I love the year here on Earth. Any light cast on my shadow is, in advance, very much appreciated.
