 | | Maine at Farmington 2JPL/Caltech Recent spacecraft-derived results on the composition of near-Ear thasteroid (NEA) 433 Eros permit the first independent check on the method used to date for deriving near-surface solid densities of radar-detected asteroids. |
 | | We use radar albedos estimated for thirty-six main-belt asteroids (MBAs) and nine near-Earth asteroids (433 Eros, 1862 Apollo, 2063 Bacchus, 2100 Ra-Shalom, 3199 Nefertiti, 4179 Toutatis, 4769 Castalia, 6178 1986 DA, and 6489 Golevka) to estimate such densities in two ways. |
 | | One method, similar to algorithms employed in previous work, uses a series of relationships between radar albedo, Fresnel reflectivity, and surface bulk density, plus the assumption of lunar regolith porosity. |
