Oh, this is SO cool! Thanks, you-all! The tilt of the earth, and also the elliptical orbit. Neat! #87719 - 11/19/03 10:55 PM Re: analemma   Joined: Jan 2001 Posts: 13,858 wwh Carpal Tunnel wwh   Carpal Tunnel Joined: Jan 2001 Posts: 13,858 I've got it! One of the few things I remember from calculus over sixty years ago is: "Always examine the means and the extremes." Suppose the earth's orbit were a perfect circle, and you were able to turn the sun into a huge stroboscope, that flashed only once in twenty four hours, and had it synch'd so the blip hit on the Greenwich meridian vertically. If you could instantly on Jan 1 turn earth's orbit into an ellipse that shortened earth's distance from the sun, the blip would arrive early. Isn't that easy to understand?
