The formula suggests that, extending outward, each planet should be approximately twice as far from the Sun as the one before. The hypothesis correctly anticipated the orbits of Ceres (in the asteroid belt) and Uranus, but failed as a predictor of Neptune's orbit. It is named after Johann Daniel Titius and Johann Elert Bode.
The average distance between Neptune and the Sun is 4.5 billion km (about 30.1 astronomical units (AU), the mean distance from the Earth to the Sun), and it completes an orbit on average every 164.79 years, subject to a variability of around ±0.1 years. The perihelion distance is 29.81 AU, and the aphelion distance is 30.33 AU.

Geographical distance or geodetic distance is the distance measured along the surface of the Earth, or the shortest arch length. The formulae in this article calculate distances between points which are defined by geographical coordinates in terms of latitude and longitude. This distance is an element in solving the second (inverse) geodetic ...
Density in g/cm 3. Diffusity in cm 3 /g. These plots show that there are a wide range of densities for planets between Earth and Neptune size, then the planets of 0.6 R Jup size are very low-density and there are very few of them, then the gas giants have a large range of densities.
This captures the relationship between the distance of planets from the Sun, and their orbital periods. Kepler enunciated in 1619 [ 16 ] this third law in a laborious attempt to determine what he viewed as the " music of the spheres " according to precise laws, and express it in terms of musical notation.
