| | E-class asteroid |
 | | E-class asteroids dominate the Hungaria group of the main belt, though some, including the two largest, (44) Nysa (see Nysa-Polana family and (64) Angelina, are found scattered further out. |
 | | Their flat reflectance spectra in the 0.3 to 1.0 micron region and high albedos suggest a connection with the aubrite (otherwise known as enstatite achondrite, hence the "E") category of meteorite. |
 | | However, this link is problematic because aubrites are clearly of igneous origin, whereas some E-class asteroids (including Nysa) show an absorption feature at 3 microns that points to water- and/or hydroxyl-bearing minerals and a non-igneous history. |
