Abstract

We investigate the distribution of extra-solar-system planets in order to search for periodicities in their distribution around their parent star. We use the database of one hundred planets outside the solar system from www.exoplanets.org and compare it along with the solar system data. We show that distribution of planets is not arbitrary and has statistically significant peaks in the histogram of distance distribution. We then derive generalized parameters for planetary distribution around a strong central object. We show that there is a statistically significant indication that the distribution in planetary orbits depends on the M?/A? planet where M? is the mass of the star and A? is the semi-major axis orbital distance of the planet.
