Notes. Perihelion distance q, aphelion distance Q, inclination i, eccentricity e, semi-major axis a (orbital elements from IAU Minor Planet Center, URL:<http://www.minorplanetcenter.net/iau/lists/TNOs.html>, accessed June 2012), color taxonomy, spectral slope, and (V − R) color index ordered according to increasing inclination. The horizontal line marks the limit of dynamically cold and hot classicals at i = 4.5° (targets in the inner belt are dynamically hot regardless of their inclination). B denotes a known binary system (Noll et al. 2008; except Varda (2003 MW₁₂) from Noll et al. 2009; and Benecchi & Sheppard 2013). Targets are located in the main classical belt unless otherwise indicated.
