Bode’s Law

Also called the Titus-Bode Law, this empirical mathematical relationship for planetary distances from the SunOur parent star. The structure of Sun's interior is the result of the hydrostatic equilibrium between gravity and the pressure of the gas. The interior consists of three shells: the core, radiative region, and convective region. Image source: http://eclipse99.nasa.gov/pages/SunActiv.html. The core is the hot, dense central region in which the was discovered by Titus in 1766 and developed further by Bode in 1772.

Start with the series 0, 3, 6, 12, 24… , add 4 to each number, and then divide by 10. The resulting values correspond to distances from the Sun for the planets and asteroid beltBelt located between 2.12 and 3.3 AU from the Sun and located between the orbits of Mars and Jupiter containing the vast majority of asteroids. The asteroid belt is also termed the main asteroid belt or main belt to distinguish it from other asteroid populations in the Solar System such Click on Term to Read More. This relationship works for Mercury out to Uranus, but fails for Neptune and beyond. A similar relationship is observed for the moons of the gas giant planets (distances measured from planetThe term "planet" originally comes from the Greek word for "wanderer" since these objects were seen to move in the sky independently from the background of fixed stars that moved together through the seasons. The IAU last defined the term planet in 2006, however the new definition has remained controversial. Click on Term to Read More).
