• SsODNet uses "Types" of objects which are all included in EPN-TAP list:

"Asteroid","Spacecraft","Comet","Exoplanet","Spacejunk","Satellite","Planet","Dwarf Planet","Star"

+ “Classes“ which are sub-division of some types:


• SsODNet uses "Classes"  of objets: ["MB", "Middle", "Inner", "Outer", "NEA", "Mars-Crosser", "Apollo", "Hungaria", "LEO", "Trojan", "Hilda", "Cybele", "KBO", "Resonant", "Aten", "HEO", "MEO", "Short-period", "Classical", "Main", "Centaur", "SDO", "Halley-type", "3:2", "Jupiter-family", "7:4", "9:5", "5:3", "Detached", "11:6", "2:1", "Long-period", "5:2", "4:3", "7:3", "19:9", "Atira", "3:1", "11:8", "5:4", "12:5", "9:4", "8:3", "11:3", "7:2"]



EPN-TAP services use target_class (nominal), dynamical_class and dynamical_type (optionals)

• Target_class for small bodies:

asteroid, dwarf_planet, comet

• Recurring pb with dwarf_planet, not always identified as such.

Baptiste proposes to set them always as  "dwarf planets#asteroid" in target_class

May solve all pb, check if this is consistent!


• TNOarecool uses dynamical_type , including res 2:5, res 1:2, Plutino, Hot classical, Cold classical, SDO (Scattered disk object), Detached object, Inner Oort obj (not strictly KBO?)

• M4ast uses no dynamic classification

• MPC uses orbit_class !!! Those are free comment strings and are not always informed (can’t be used easily for searches…)

    Include 4 NEO types + Object with perihelion distance < 1.665 AU, Hungaria, MBA, Phocaea, Hilda, Jupiter Trojan, Distant Object, Unclassified

• DynAstVO

uses dynamical_class, including TNO, MBA, NEO     + add Centaur, Trojan, OCC et JFC ?

uses NEO, MBA, null

+ dynamical_type including Athen Apollo Amor Atira, plus other things:

CENTAUR (class NULL) - should be in dynamical_class

PHOCAEA (class NULL) - are MBAs

I, IIA, IIB (MBA)

• Is there a clear IAU nomenclature with 2 sub levels?
