There are two very interesting papers on adaptive optics observations of Lutetia on arXiv today:
Physical properties of ESA/NASA Rosetta target asteroid (21) Lutetia: Shape and flyby geometry The triaxial ellipsoid dimensions, rotational pole, and bulk density of ESA/NASA Rosetta target asteroid (21) Lutetia turns out Lutetia spins on its side like Uranus, and one entire hemisphere will not be illuminated when Rosetta swings by. As for the shape, QUOTE asteroid (21) Lutetia is well described by a wedge of Camembert cheese (justifying the Parisian name of Lutetia)

From first article I made this rough animation of the rotating asteroid (time intervals aren't proportional):  North is up/above image plane EDIT: I removed second frame in order to have more fluid/consistent rotation -------------------- I always think before posting! - Marco -
