I think the term "second moon" is only because it approaches so closely (.1AU). Reading about it and watching the simulations, it is clearly not orbiting the Earth as we keep passing through its orbital plane.

An Earth moon has to orbit the Earth. I thought that was obvious to everyone? Why are they calling this Earth's 2nd moon if it does not orbit Earth?
