 The LCDB assumes a stony (S) or carbonaceous (C) composition to be equally likely, while the overall spectral type for members of the Aeria family is that of an X-type.The high albedo figures obtained from observations with the WISE telescope do not agree with neither of these spectral types "(see below)".In January 2011, a rotational lightcurve of "Gaea" was obtained from photometric observations by French amateur astronomer René Roy.
