The asteroid was named after Honoria, granddaughter of the Roman Emperor Theodosius I, who started negotiations with Attila the Hun. It is classified as a stony S-type asteroid based upon its spectrum. Polarimetric study of this asteroid reveals anomalous properties that suggests the regolith consists of a mixture of low and high albedo material. This may have been caused by fragmentation of an asteroid substrate with the spectral properties of CO3/CV3 carbonaceous chondrites.[2]References1. ^1 {{Citation | last1 = Gil-Hutton | first1 = R. | last2 = Mesa | first2 = V. | last3 = Cellino | first3 = A. | last4 = Bendjoya | first4 = P. | last5 = Peñaloza | first5 = L. | last6 = Lovos | first6 = F. | display-authors = 1 | title = New cases of unusual polarimetric behavior in asteroids | work = Astronomy and Astrophysics | volume = 482 | issue = 1 | pages = 309–314 |date=April 2008 | doi = 10.1051/0004-6361:20078965 | bibcode = 2008A&A...482..309G | postscript= .}} [1]}} External links
