532 Herculina
Recent (2002) modelling of photometric data shows that Herculina is not spherical, but a blocky shape not unlike a battered cuboid - or, as the analysis described it, it "resembles a toaster". This analysis indicates the presence of many big craters, similar to 253 Mathilde, but no major changes in albedo. The approximate ratios of the axes were suggested as 1:1.1:1.3, broadly consistent with earlier models if a bit more stretched.
