Pluto is so different from the giant planets that since Clyde Tomb discovered it in 1930, various hypotheses about the origins of Pluto have been put forward many times. It is known that Pluto's position with the solar system contradicts the empirical rule of Titius-Baudet, which predicts for it a large axis of the orbit of 77 a.u. (at the actual value of 39.4 a.u.). For Neptune, too, there is no good match: 30,1 a.u. instead of the predicted 38,8 a.u. But the position of planetary orbits is actually determined by the theory of resonances, and the rule of Titius-Bode is his special case...
