i prefer the term 'binary planet'.

also due to the Moon slowly migrating away from us, in a few hundred million years the centre of mass in the Earth-Moon system will lie outside the Earth, making it a binary planet.

>Though not an official classification, the European Space Agency has referred to the Earth–Moon system as a double planet. The IAU General Assembly in August 2006 considered a proposal that Pluto and Charon be reclassified as a double planet.
