The Bode-Titius Law gives a pretty fair approximation of the radiuses of the orbits of the planets. It appears to fail between Mars and Jupiter but that is where there are many asteroids and where they would have combined to form a planet if Jupiter was not so close by. The Law fails to give the right figure for Neptune but Pluto fits the value given by the law quite well. Astronomers think that Pluto is not a true planet but an escaped moon of one of the planets. As remarkable as the Bode-Titius Law is for predicting the orbit radiuses of the planets there is no explanation of the law in terms of other laws of physics.
