Abstract Earth-based spectral measurements and NEAR Shoemaker magnetometer, X-ray, and near-infrared spectrometer data are all consistent with Eros having a bulk composition and mineralogy similar to ordinary chondrite meteorites (OC). By comparing the bulk density of 433 Eros (2.67±0.03 g/cm 3 ) with that of OCs (3.40 g/cm 3 ), we estimate the total porosity of the asteroid to be 21–33%. Macro (or structural) porosity, best estimated to be ∼20%, is constrained to be between 6 and 33%. We… Expand
