Re: Large Satellites?
Or isn't the Earth a body that orbits the Moon? Just like two masses of whatever size have equal gravitational attraction, so two bodies in close proximity equally orbit each other. Because we earthlings have a geocentric viewpoint, we like to think the moon orbits the Earth but in fact they orbit each other and the Sun in a spiral corkscrew pattern. Likewise the planets orbit the Sun and together the bodies in the solar system orbit the Milky way in a corkscrew fashion.
So, why shouldn't the Moon be classified as a co-planet!
