No, you are the one that said that you didn't know how to model the two stationary bodies with one rotating. However you did say that if the Sun were orbiting the Earth then it would have a 2.1 degree lag. Show that.
You will find there is no difference in the two models : )
Fascinating animation; the rotating image of the earth looks like a hampster wheel with a donkey doing the driving, trying to get away from the miniature poodle who has hold of the donkey’s tail while a beaver is desperately trying to overcome the force holding him in place so that he can bite the donkey in the middle of the back.
How come you didn't provide a degree with your angle of impact?
Could it be because what you call the angle of impact is 2.1 degrees : )
Hoisted by your own petard?
No need to. The animation that you provided shows the correctness of 2.1 degrees.
