The orbit is straight, it's the earth that is rolling in its daily wobble. The earth is tilted at approximately 23 degrees from the plane of the ecliptic, and it wobbles. Look at orbits going back to our very first satellites and space capsules, they all had that "sine wave" look to them. The earth's spin is not stable like a spinning top. If I remember my Astronomy 101, I think it's call "precession".... the way the earth wobbles as it spins.

Ohhh, of course, I feel like an idiot now...
Thanks for clearing that up.
Not at all, everyone of us brings different skill sets to GA... carry on, anon.
