EVERY orbit is elliptical.

100km X 30km are ELEVATIONS, meaning the real orbit is diameter of Moon + 100km X diameter of Moon + 30km.

If you had this scaled and drawn on a sheet of you would need very accurate instrument to detect any deviation from perfect circle.

> real orbit is diameter of Moon + 100km X diameter of Moon + 30km.

3,574km X 3,504km

That helped me a bit.

So maybe not so precise instrument, but still, if this was 15cm ellipse the difference would be about 1mm.

Yes, that makes sense.

100km x 30km orbit around moon, what was I thinking - facepalm (－‸ლ)
