    to form the two moons in the first place? Mars? An Oort object?

    Well? Shall we go? At least that man is gone.

      That is cool too because it seems likely that it was in a shared orbit. Over time it over took the Earth, but it likely formed right here where we are.

      Until just recently we had never seen co-orbiting planets, but we found a set at another star so it has given the theory a big boost.

      After all anything moving through the Solar System that is not in orbit and was that size would have knocked the Earth out of its orbit.

      Getting Democrats together and keeping them that way is like herding cats that are high on meth, through L.A., during an earthquake, in the rain -6.25, -6.10
