Only major problem i have with ESB is when Han suddenly decides to walk out to (as far as he know) a cave inside an asteroid in OUTER SPACE, in a vaccuum, with nothing but a breathing mask, oh and gravity on the asteroid is perfect as well. At least inside the ship they have the excuse of artificial gravity. But then again there's not much one can do to that scene.

One could argue that the asteroid is large enough to exert some gravitational pull, and therefore hold an atmosphere of sorts, albeit a thin one (hence why our heroes need to wear breathing masks). If this were the case, then I'm sure Han could have verified this on the Falcon's instruments before venturing outside.al physical laws.

Surprisingly, the main reason why they went outside is missing, the mynoks flying around... :) Our heros (Han, at least) don´t seem to be too much surprised to see living creatures deep inside a huge asteroid in deep space, as if asteroids with some gravity, atmosphere and even an ecosystem are common place... :)
