Planets don't have planets. The Sun has planets, and planets have moons.Dwarf planets might orbit around each other, but this answer uses the correct definition of the term planet, which does not include Pluto or Charon.
Planets cannot have stars orbiting them by definition.
They agreed a new definition of a planets and created "dwarf planets" as a separate type of object. Pluto qualified only as a "dwarf planet", because it is not the dominant object in the neighbourhood of its orbit.
Because there are only eight planets in our solar system, a definition of "top" would be needed - since the definition would thus have to include exoplanets discovered outside the solar system.
Well, we cannot say that they are two new planets but they are new discoveries and considered as dwarf planets. Xena and Ceres
