I know we've obtained some images of asteroids from probes. Since each of those constitutes a fairly costly and public mission, I wonder if it would be possible to get a list of all such objects that have been imaged, as of this year, 2013? Just a text-based list of the IAU names would be fine.
If this would be more than 10 or 20, then I'll gladly withdraw this question. I ask because I don't think that's the case.
Aside from probes equipped with a camera, is there any other source of direct images of asteroids? I know there is radio astronomy as well as other computational methods to approximate the shape from varying intensity over time. The number "imaged" by those methods would be more difficult to pin down, so let's exclude those. But did Hubble image near Earth asteroids?
