Abstract

The existence of opposite fore’s acting on astrophysical bodies, involve that their properties should  obey  to  oscillation  symmetry.  The  oscillation  symmetry  is  applied  to  several  astrophysical properties, like Nebulae radii and magnitudes, Local Group Galaxy masses, luminosities,  and  diameters,  Comet  radii,  orbital  periods,  and  eccentricities,  Black  hole  masses,  orbital  periods,  and  distance  from  earth,  Star  masses,  magnitudes,  and  distances  from  Sun.  This  symmetry  is  used  to  predict  some  still  unknown  astronomical  properties,  namely the properties of two additional possible solar planets. Using the predicted possible masses  of  these  planets  the  method  allows  to  predict  their  possible  densities,  rotation  durations, revolution periods, orbital speeds, and eccentricities.
