This isn't artificial gravity, its just rotational force. The wikipedia article even suggests that the solution to motion sickness is slower rotation, achievable with larger diameters. https://en.wikipedia.org/wiki/Rotational_gravity https://en.wikipedia.org/wiki/Rotational_gravity Says it takes a ~224M radius at 2 rpm to get earth gravity. Given the ISS is 108M wide seems pretty doable with current technology if we really wanted to. There is also a pretty interesting chart here https://ase.tufts.edu/cosmos/view_picture.asp?id=748 https://ase.tufts.edu/cosmos/view_picture.asp?id=748 about asteroid size vs rotational speed.
