The spacings of the planetary orbits are divided into three sequences, 1) equal differences ~.3 AU between Mercury, Venus and Earth, 2) equal-- 9.6 AU (32 times the former) between Uranus, Neptune and Pluto, and 3) the doubling of orbit spacings between Earth- Mars ~.6 AU ; Mars - Asteroids ~1.2 AU ; Asteroids - Jupiter ~2.4 AU; Jupiter - Saturn ~4.8 AU and Saturn -Uranus ~9.6 AU. The doubling sequence has it's 0, zero starting point at Venus, and ends at Uranus, both planets being bracketed by equal distance neighbours. interestingly, These two planets, Venus and Uranus, also happen to be the ones with retrograde rotation, possibly though,- from different causes. so: coincidences that are indicators of the causes of present stability ? *revisited from the cesspool. and the related Newton's Pebbles. thank you. may be they are related they definitely are linked.
Er, no. The distance between Mercury and Venus is 0.336 AU and between Venus and Earth is 0.277 AU, this is a difference of 20%, and hardly equal. The Earth Mars distance is 0.523 AU not 0.6 that's nearly a 14% difference. The asteroids belt extends from~2.1-3.3 AU, the median is 2.7 AU, But that is still a pretty large range. Even if you use the median for the asteroid belt distance, the Mars- Asteroid belt distance is 2.25 times the Earth Mars distance not 2 times, The asteroid-Jupiter distance is 2.5 AU which 4.78 times the Earth-Mars distance, the Jupiter-Saturn distance is 4.35 AU or 8.3 times The Earth-Mars distance, The Saturn-Uranus distance is 9.6 AU , but this is 18.4 times the Earth- Mars distance. the 2.25-4.78-8.3-18.4 ratio sequence is 2.12, 1.74, 2.22. You can only say that this is 2 if you are really liberal with your definition of "2" The AU distances between The respective distances for the outer planets is Saturn-9.6AU-Uranus-10.9 AU-Neptune-9.42 AU-Pluto. That's still a 16 percent difference between the smallest and largest distance. You can can find all kinds of "coincidences" if you are allowed to fudge your number by that much.
Janus, This broad stroke idea is not about the bode law, that sees only 5% max deviation from the theoretical to measured values, but the "coincident", that the two retrograde planets also sit at the beginning and end of the doubling of the distance sequence (3), and are bracketed by same distance spacings. The doubling of the planetary orbits starts with a retrograde planet, Venus, and finishes with another odd one, Uranus. as to divergence quibbling: Earth 1, Mars 1.6 according to Bode, 1.54 real, a 4.9% difference. The ones that really counts, Jupiter, bode: 5,2, real 5.203, a .o.05% difference, the Earth right on. Scattering is common in all measurements. A strohman diversion tactic. address the issue please. .
alternate amendment to the bode law: if a planet has a retrograde rotation, it has 1) two adjacent planets that are equidistant, and 2) one of these adjacent planets has a neighbour planet that is distant at a ratio 2:1 .
