You've meant event horizon diameter, I suppose. BH alone should be much, much smaller than that

Yeah, it's about the only useful size you can have about them, since information coming from inside the event horizon is a bit scarce.

For some reason, I am now fighting the urge to compare FD posts to Hawking radiation..
OK..this answers my question on how close you can get (went out to scout my first black hole..but since I wanted to get the data back I didn't dare approach closer than 40km when temperature started to rise slightly)
What would a 'non-broken' black hole look like? Do you get the yellow exclusion zone you get with planets/stars when you get very close? Or can you really just run over/through them without any ill effect?

According to Einstein a black hole really should just look like a star frozen in time. Since when a black hole forms all light cannot escape and time would seem to stand still for anyone viewing it from outside the event horizon the instant it is created. If you move passed the event horizon the black hole you will suddenly see it for the brief millisecond before it tears your atoms apart. Mother natures ultimate trap.
But one that is invisible after a very, very short time. The 'frozen image' of a star does not continue to produce photons (the collapsing star may - inside the black hole - but those you never get to see outside in any case). What would appear 'frozen in time' is just the part that is emitted right as the star contracts through its event horizon. More precisely the photons that are emitted just a teeenzy weenzy bit outside the event horizon at the moment and fully in radial direction. You can imagine that the number of photons that qualify for this are very few.
You would also not see anything because:
1) Each photon that is viewed (or just happens to impact on an infalling particle) reduces the number that can be viewed in the future
2) Each photon would get continually redshifted until viewed (i.e. if you don't look at it seconds after the black hole formed the photon would be so far redshifted that it would not register on any conceivable device)
So yeah: while the 'frozen star' is a conceptual reality in real actuality you'll see nothing of the sort.

Not neccessarily
. While the infinitessimally small singularity appears in theory, all we know about celestial black holes is that their physical extent is constrained within the event horizon. There's plenty of evidence that black holes exist, but not neccessarily what we think of

The closest one I've ever moved to was one in the NGC 7822 nebula - I think I was able to move within 9m range (kind of "taking it onboard" so to speak).
Still, it wouldn't fit into the Cargo Scoop (I tried)
PS.
I hope we'll one day see Black Holes doing crazy and dangerous stuff to the Ship when getting too close.
Always feels awkward sitting steady in normal space and there's basically 0 Gravitational effects from them
I agree BH's are super scary, but in elite, not so much...
Or is it a craphics bug
According to the Schwarzschild metric (a common spherically symmetric spacetime metric in General Relativity), the event horizon of a Black Hole (or Schwarzschild radius) is at R = 2*G*M/(c^2), where G is Newton's grav. constant, c the speed of light and M is the mass of the BH. So for a mass of 12.7 solar masses the event horizon is at a distance from the center of the BH R = 37.3 km. So, yeah, anything below that means you should be inside the event horizon and not be able to relay any information to any outside observer. But since you are able to communicate still, can you make a couple of experiments and help us understand the physics of the interior of a BH?
Ask your mother.
