Editing Classical Kuiper belt object (section)

=== SSBN07 classification ===
An alternative classification, introduced by [[Brett J. Gladman|B. Gladman]], [[Brian G. Marsden|B. Marsden]] and C. van Laerhoven in 2007, uses a 10-million-year orbit integration instead of the Tisserand's parameter. Classical objects are defined as not resonant and not being currently scattered by Neptune.<ref name="ArizonaBook_Gladman2007">

Formally, this definition includes as ''classical'' all objects with their ''current'' orbits that
*are non-resonant (see the [[Resonant trans-Neptunian object#Classification methods|definition of the method]])
*have a semi-major axis greater than that of Neptune (30.1 AU; i.e. excluding centaurs) but less than 2000 AU (to exclude inner-Oort-cloud objects)
*are not being scattered by Neptune
*have their eccentricity <math>e < 0.240</math> (to exclude detached objects)
Unlike other schemes, this definition includes the objects with major semi-axis less than 39.4 AU (2:3 resonance)—termed '''''inner classical belt''''', or more than 48.7 (1:2 resonance) – termed '''''outer classical belt''''', and reserves the term '''''main classical belt''''' for the orbits between these two resonances.<ref name="ArizonaBook_Gladman2007" />
