Few realise the gravitation of the situation, for the laws of physics agree with politically correct renomination as "sister planet" (though how does one engender gender of any cosmic member?)
You see that if the Earth you be then the Sun, the moon attracts more than thee. By Jove there are faithful moons a plenty, others weave the rings of Saturn, even Neptune has proper moons to see but alas that moon of Earth, the original sample , is near twice acolyte to Ra, despite Earth's proximity seeming ample. Not perihelion nor even aphelion shake this double grip from afar, not inverse square of the distance there can compensate the mass of star.
So now its time the numbers are begun, Let the mass of Earth be one!
SUN MOON SM/EM Mass 333,000 0.012 Distances Min 152,100,000 356,399 1.82 Mean 150,000,000 384,403 2.19 Max 147,100,000 406,699 2.56The min mean max in kilometres be, whilst third of columns is Ra's superiority to Earth's lunar attractivity, forced by mass times inverse square of all those numbers mentioned there, contrived to give the smallest min and the greatest max the formulation no real mental tax.
Despite this tortured ditty it is reason brokered by nature which comes out pretty. What use is this accountants ask, none to them whose life is but financial farce and what of art, that anthropic thing whose cause for proof is trifling thin... I just thought I'd get a dig in!
