Editing Classical Kuiper belt object (section)

=== DES classification ===
Introduced by the report from the [[Deep Ecliptic Survey]] by J. L. Elliott et al. in 2005 uses formal criteria based on the mean orbital parameters.<ref name="DES_Elliot2006" /> Put informally, the definition includes the objects that have never crossed the orbit of Neptune. According to this definition, an object qualifies as a classical KBO if:
* it is not [[Resonant trans-Neptunian object|resonant]]
* its average [[Tisserand's parameter]] with respect to Neptune exceeds 3
* its average eccentricity is less than 0.2.
