The second largest and the second asteroid, Pallas, has been observed by the Hubble Space Telescope (http://www.planetary.org/blog/article/00001695/) which has been able to discern some details. Looks like it has somewhat lumpy shape, though not as pronounced as Vesta. In overall, it seems to be intermediate between icy, spherical Ceres and basalt-rich, rocky Vesta.

The irregular shape of Pallas and Vesta means they will not get the dwarf planet status despite the fact that both are more massive than Saturn's moon Enceladus, which is round. This is because Enceladus is mostly ice whereas Pallas and especially Vesta consist of rock.

Very nice. Let's hope that a few years from now nobody in a control room will have to yell "STEEeee-RIKE!".
