HST and radar shape models.

HST shape model (Lamy et al. 2008a)
Shape Two spheres in contact
Largest sphere (radius) 2.8 km
Smallest sphere (radius) 1.2 km
Pole orientation RA = 285 ± 12° and Dec = +20 ± 5°

Radar shape model (Harmon et al. 2010)
Shape Two prolate spheroids in contact, aligned along their long axis
Largest spheroid (semi-axis) 2.06 × 2.06 × 2.88 km
Smallest spheroid (semi-axis) 1.64 × 1.64 × 2.13 km
Pole axis Perpendicular to the long axis
Pole orientation RA = 268 ± 5° and Dec = −16 ± 2° (this work)
