Continuing our quest to understand more about planetary frequencies, we turn to links between the largest planet Jupiter and the two ‘outer’ giant planets, Uranus and Neptune.
This model is based on a match of synodic periods, which is found to be:
22 Uranus-Neptune (U-N) = 273 Jupiter-Uranus (J-U) = 295 Jupiter-Neptune (J-N)
The period is just under 3771 years (~3770.93y).
To find a link to Fibonacci numbers we can look first at Jupiter-Uranus:
273 J-U = 13 x 21 (13 and 21 are Fibonacci numbers)
The 295 J-N is the sum of 22 (U-N) and 273 (J-U), as it must be if the periods match.
The 22 U-N is 21 + 1, and 295 J-N is 14 x 21, + 1.
If we look at the orbits in the period, a pattern emerges:
Neptune = 22.8831
Uranus = 44.883
Jupiter = 317.8834
Note the decimal places are almost identical.
In the chart the decimal places are reduced to three for clarity.
So the main point of this post is that the J-U-N synodic frequencies are tied to a multiple of 13 x 21 Jupiter-Uranus conjunctions.
Now let’s take a closer look at the orbit numbers.
Multiplying by 60 brings the planets close to whole numbers. Also:
22 U-N x 60 = 1320 = 3 x 8 x 55 U-N
3, 8 and 55 are Fibonacci numbers.
However a closer fit is achieved with 77 as the multiplier.
That’s because 68/77 = 0.8831168, almost identical to the decimal place values above.
(Incidentally 68 = 34 x 2 which are both Fibonacci numbers).
An expanded model with 77 times the values of the original, has whole numbers of orbits:
1762 N — 3456 U — 24477 J
(55×32,+2) (144x8x3) (144x34x5,-3)
(The synodic numbers were already whole, so just increase by a factor of 77).
Now we have Uranus with an exact multiple of Fibonacci numbers: 3,8 and 144.
Neptune and Jupiter are very slightly offset from Fibonacci multiples: N by 2, J by 3.
N = 55 x 8 x 2 x 2, plus 2.
J = 144 x 34 x 5, minus 3.
2,3,5,8,34,55 and 144 are all Fibonacci numbers.
