Ah! Got it now, the pivotal characteristic of the system is really the density of the objects (especially the large one). So for my spiragraph orbit to work nicely, I need a (lets assume star) that is far denser than Sol (at a similar mass) or of a similar density but much heavier (the radius...

Please excuse my over simplistic statement. My mind was trapped in '2d in plane orbit / de-orbit thinking' ---------- Post added at 02:58 PM ---------- Previous post was at 02:52 PM ---------- I read into this that the more delta-v the quicker the flight to the surface. Coincidentally, I...

This is what I was getting at. Yes, I understand that that must be true. My thinking was as follows: I keep reading that the most efficient place to burn fuel is when the vehicle is going at its fastest. In the 'lazy de-orbit' scenario I imagined, the vehicle would be going fastest just...

This is getting interesting So the effects of 'Relativistic precision' are apparent in the Mercury=>Sol orbit because: A. They are close to each other & B. Sol is much bigger than Mercury. You mention massive singularities so I am guessing that the more extreme the mass ratio the stronger the...

Scenario: An orbiting station or habitat. A small vessel wishes to leave and return to the planet's surface. Initial assumptions: The habitat rotates to produce 1g acceleration for inhabitants. The rotation axis of the planet and habitat are parallel. The habitat orbits on the equatorial plane...

I am imagining a stable orbit pattern something like this. The large object might be a plant (as labelled) or a star. The small object might be a space craft (as labelled) or a natural satellite. The orbiting object makes an almost complete orbit at highspeed near the closest point and then...

Hello to all the lovely wonderful people here on the orbiter forum. I have some (limited?) understanding of physics from my training as a mechanical engineer, though I have become a bit rusty after 15 years in technical sales. Currently, I am writing a sci-fi novel (several in parallel in...
