by 4+3=7 such parts, the Earth by 4+6=10, Mars by 4+12=16. But notice that from Mars to Jupiter there comes a deviation from this so exact progression. From Mars there follows a space of 4+24=28 such parts, but so far no planet was sighted there. But should the Lord Architect have left that space empty? Not at all. Let us therefore assume that this space without doubt belongs to the still undiscovered satellites of Mars, let us also add that perhaps Jupiter still has around itself some smaller ones which have not been sighted yet by any telescope. Next to this for us still unexplored space there rises Jupiter's sphere of influence at 4+48=52 parts; and that of Saturn at 4+96=100 parts.

These were the extremes among planets known in 1913, and an astronomer would not have any reason to choose a range of "multiplier" values wider than the one dictated by Venus/Uranus on one end and Mars on the other.

Can one believe that the Founder of the universe had left this space empty? Certainly not. From here we come to the distance of Jupiter by 4+48=52 parts, and finally to that of Saturn by 4+96=100 parts.

Neptune's distance was very discrepant, however, and indeed Pluto – no longer considered a planet – is at a mean distance that roughly corresponds to that the Titius–Bode law predicted for the next planet out from Uranus. 3861:

At its core, the formula uses a progression ratio of 1.7275. This does not fit the data - for example, Venus and Uranus have semimajor axes higher than predicted, and Mars has a semimajor axis lower than predicted.

This latter point seems in particular to follow from the astonishing relation which the known six planets observe in their distances from the Sun. Let the distance from the Sun to Saturn be taken as 100, then Mercury is separated by 4 such parts from the Sun. Venus is 4+3=7. The Earth 4+6=10. Mars

In the paper, the exact form of the 7-term function (and its bending down toward zero in the region where Eris is located) was justified by desire to fit certain moons of Jupiter and Saturn (J3, S8) on the graph. But these moons can be put on the function graph quite arbitrarily, depending of the

Roy found that all six fitted very closely. This might have been an exaggeration: out of these six bodies, four were sharing positions with objects that were already known in 1913; concerning the two others, there was a ~6% overestimate for Pluto; and later, a 6% underestimate for Miranda became

Yet the author of the formula clearly knew about Eris, and adjusted the range of possible "multiplier" values accordingly. The formula was created so that the lower end of the range of possible "multiplier" values was Eris, nor Mars. The 7-term function (the "multiplier" being simply this 7-term

As it turns out, this formula also gives the distances of (then-unknown) objects at n=7 and n=8 as 42.00 AU and 67.07 AU, respectively. Therefore, this supposedly 1913 paper predicts the semimajor axis of Eris with uncanny accuracy, with an error of only about 1%.
