The outer reaches of the Solar System are residence to the icy bodies known as trans-Neptunian objects (TNOs). Implications such as low albedo and size have left this field relatively unexplored and in turn, encouraged the pursuit of these far-orbiting objects. A database of 48 objects was used by Fulchignoni et al. (2008) to cluster, model, and analyze the various spectra into classified taxa. The dataset adopted by Fulchignoni et al. (2008) was used as a baseline for visual colors to which Dalle Ore et al. (in prep) provided the significance of adding albedo measurements taken from Stansberry et al (2008). To further the classification accuracy, two near-infrared color bands from the Spitzer Space Telescope, centered at 3.55 and 4.50 microns, were supplemented with the previous 7-filter photometry. The 9-band compilation produced altered results from the previous studies; the addition of Spitzer data hopes to distinguish varying compositional properties of icy objects. We present a redefined taxonomy that may uncover clues to evolutionary trends of the TNO population.
