wonder if this applies to Charon
funny, though, because we still don't have very good pics of Pluto, at least 'till New Horizons reaches it...
If I remember correctly, the best "picture" they could get of Pluto was from a non Hubble telescope, which gave us a few pixel resolution picture of Pluto.
Ah there we go. Apparently there is a Hubble based picture of Pluto, though barely enough to actually see the planet. I think it is due to how Hubble is designed for seeing things very very much farther than Pluto, so it cannot focus on something as close as Pluto?
