I do wonder where the idea of comets orbiting the Sun in a FE model comes from, though. I didn't know there was anything that suggests the Sun had an attractive force, beyond the slight effect on the planet's tides. But then, shouldn't it be orbiting the Moon? That has a far greater apparent attraction in a FE model.
Perhaps I don't understand what FE'ers define as an orbit. Is a FE orbit different to a RE orbit?
