How wide is a pencil mark depicting the orbit of Terra on a sheet of 8 1/2 x 11" piece of paper, scaled to size? How does that compare to the actual orbit of Terra?
Physics TA... is a circle an ellipse?
Cooks know the answer to that question.
But the question is, granting that the earth’s orbit is an ellipse, how close is it to a circle? I’m saying that it is so close that it would, to scale, easily fit within an 8” diameter circle formed by an 0.5mm pencil line. OK?
