    Some asteroids aren't rocks. They are rubble heaps. This makes sense when you think about it. These asteroids may have never been a part of a large terrestrial like body with gravity like earth. They are just loosely held together by their own modest mass.

    For some reason I find this revelation creepy. I suppose I think about trying to land on the surface and just sinking ...

      @futurebird You might get some vacuum welding too. So a brittle crust that you could break through by, say, stepping on it.

              @futurebird
              This is a fact that I haven't seen explored in most sci-fi stories with asteroids. It brings a new adversarial envrionment..

                @RogerBW @futurebird that is pretty much what they found out when they sent that probe to take a sample of an asteroid. they are not necessarily very dense.

                      @futurebird "sinking" isn't the right word. "Penetrating" possibly: you're a projectile shooting into the asteroid, disrupting it.

                          @RogerBW @futurebird pushing off it, surely? You'd break the crust but achieve escape velocity doing it?

                            @futurebird I doubt they'd have enough gravity for you to sink. It's probably more likely that you'd bounce off into space (very slowly).

                              @futurebird this might be very beneficial for some sci-fi level asteroid mining, you don't have to do actual drilling but "just" turn the whole thing inside out somehow™ until you can scoop up the good parts

                                        Quite a while ago now; I was involved with a NASA mission plan called the Asteroid Redirect Mission, which would have demonstrated gravity tractor asteroid deflection as well as space resource utilization.

                                        The plan was to pick up either an entire small asteroid or a boulder from a larger asteroid. To deal with even what looked like a single block potentially being only loosely held together, it would have been enclosed in a large bag to contain all the shed bits.
