Well, if there's not much around it, it might be hard to detect it's gravitational effects.
I'd imagine you could detect it blocking a circular patch of sky more easily and from farther off than you could detect the gravitational pull on your spacecraft.
Just don't steer twords the black disc and you'll be fine.
- zaarn 8y agoI think not steering towards the black disc is a good advice for space travel in general...
- captn3m0 8y agoBut you can use it for gravitational slingshots.
- ben_w 8y agoFour ships (or a ship and three probes) arranged in a tetrahedron, where the distance between each pair is precisely measured with a laser or similar. Changes to the edge lengths of the formation show a nearby gravity gradient. What’s one wavelength per minute if the formation is 1000km?
- dragonwriter 8y ago> Changes to the edge lengths of the formation show a nearby gravity gradient. Or changes in density or relative velocity of the interstellar medium, etc.; gravity isn't the only feature that can alter the formation.
- ben_w 8y agoTrue, although I expect the ISM pressure to be fairly directly measurable. I wonder what the magnitude of all possible affecting things is compared to the gravity of planet like objects at various distances…
