Planet_and_Asteroid_Periods_according_to_DE441

By plotting data from DE441 and sb441-n373, the overall trend of the accumulated advance of the Mean Longitude of each of the Planets and Asteroids is gauged across the full span of each ephemeris (30,200 and 17,000 years respectively).The numerical values of Period over such a long time span are precise enough so that those values can be used as a label to sort the Solar Sytem objects more uniquely and repeatably than otherwise possible. The result will also be useful for more accurately drawn Period-Eccentricity diagrams. In schools when "Bode's Law" is discussed these data might contribute. I hope to do a follow-up paper for the parameters "semi-major axis", "mean distance", and "eccentricity" on this same [DE441,sb441-n373] data set.
