Quick Reference

A rare class of asteroid whose members have a featureless reflectance spectrum, flat to slightly reddish over the wavelength range 0.3–1.1 άm. E-class asteroids are distinguished from the spectrally identical classes M and P by their higher albedos (0.25–0.60). The E is for enstatite, since they are believed to have surfaces that are similar in composition to enstatite achondrite meteorites (see aubrite). Members of this class include (44) Nysa, diameter 70 km, and (214) Aschera, diameter 23 km.
