The relative size of earth and moon are a little bit of close in astronomical world.One can find unique relationship between two planetary systems i.e the earth and moon.

In astrophysics the term binary planet system refers to two planets.Here both the planets are of planetary masses.Two planetary bodies will be considered as the binary system if their sizes are proportional to each other and comparable.

Moon is the one satellite in the entire solar system which is larger than other satellites.The weight of the earth is 81 times more than the weight of earth and it is just 384000 km away from earth .Ideally it can not be considered as binary planet system.But it is considered as a binary planet system as their relative size are so close.

Hence the answer of this question is binary planet system.
