Cubesats are (ir-)regularly deployed at very low velocity from the ISS, and they don't usually have propulsion. This tells me that the delta-v is enough to guarantee to those in charge that their orbits won't intersect the ISS again.
A tool bag "got away" - I saw this in a text book.
I remember an ISS astronaut deploying something intentionally by hand - I think it was a nano-satellite of some kind, maybe a self-deorbit experiment?
But these are just from memory.
What kinds of things have been tossed out of - or otherwise intentionally deployed from - the ISS?
edit: I don't want a list of everything - well yes I do, but I'm not asking here for a list of everything. I'm guessing there may be 3 to 6 different classes of things. Cubesats would be one classs. Space suits would be one class, waste would be one (hypothetical) class, for example.
edit: I found this YouTube linked in this discussion of some examples just for example(s).
