Can you turn off your ship in space and park it on an Asteroid for example, making it non-detectable except visually?asked by Dalphon

Dan Tracey: Probably signals.

Yeah, we've got our signal system set up so that if you're not emitting IR or EM radiation and you've only got your cross-section (visual) then you'll be much harder to find. And if you're really close to something like an asteroid with a large and noisy cross-section, then you'll be really hard to find with all the noise that creates. Which you'd expect! You could easily miss if a ship was there, that asteroid is bumpy. A resounding yes, in sum.
