  We calculate the ground state properties of recently synthesized superheavy
nuclei starting from $Z$=105-120. The nonrelativistic and relativistic mean
field formalisms is used to evaluate the binding energy, charge radius,
quadrupole deformation parameter and the density distribution of nucleons. We
analyzed the stability of the nuclei based on the binding energy and neutron to
proton ratio. We also studied the bubble structure of the nucleus which reveals
about the special features of the superheavy nucleus.
