Shape model of asteroid (21) Lutetia (left). Shape model of asteroid (2867) Šteins (right). The models are based on in situ images obtained by the Rosetta space mission. In the panels, the top and bottom plates on the left correspond to polar views along the z-axis (axis of rotation). The top (bottom) plates in the middle and to the right correspond to viewing along the x-axis (y-axis).
