The Titus-Bode-Phillips Principle (Slide 5 of our Asteroid and Comet Lecture) suggests if you take the numerical sequence 0, 3, 6, 12, 24 (and so on); then add 4 and divide by 10 you obtain 0.38, 0.7, 1, 1.6, 2.8; which are good approximations for the distances from the Sun to all the recognized planets/dwarf planets in astronomical units (AU). Predicted distance (AU) Actual Distance (AU) 0.38 0.39 Mercury 0.70 0.72 Venus 1.00 1.00 Earth 1.6 1.52 Mars 2.80 2.77 Asteroids 5.20 5.20 Jupiter 10.00 9.54 Saturn 19.60 19.19 Uranus 38.80 30.07 Neptune Planet Nine is speculated to be on average 20 times farther away from the Sun than Neptune (on average distance from the Sun). How many miles from the Sun would this place Planet Nine on average? Divide 93 million miles into your result to get how many astronomical units (AU) Planet Nine would be on average away from the Sun. Now, calculate out the Titus-Bode-Phillips Principle AU value until you get a number where your previous calculations suggest is the AU value for Planet Nine. Is your TBP value close or wildly off? Does the TBP Principle hold-up for the current suggestions for Planet Nine’s distance from the Sun? As you can see by the chart above, Neptune’s position is not consistent with the Titus-Bode-Philips Principle. Run the distance calculations instead from Uranus and see how your values turn out.
