NLR190 is a spherical harmonic model to degree and order 24 based on approximately 5 million Eros radii collected by the NLR through day 190, year 2000. Because of its deviation from sphericity, on Eros one degree varies from about 54 to 307 m.

The table below shows the moments of inertia of 433 Eros from NLR190, assuming that the asteroid has a constant density.
