kepler used the data from tycho blahe (his mentor) to construct the laws of planetary motion.

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees.
