Notable Trans-Neptunian Objects

• Pluto, a dwarf planet.
  • Charon, the largest of Pluto's moons.
• (15760) 1992 QB₁, the prototype cubewano, the first Kuiper belt object discovered after Pluto and Charon.
• 1998 WW₃₁, the first binary Kuiper belt object discovered after Pluto and Charon.
• (15874) 1996 TL₆₆, the first object to be identified as a scattered disc object.
• (48639) 1995 TL₈ has a very large satellite and is the earliest discovered scattered disc object.
• 1993 RO, the next plutino discovered after Pluto.
• 20000 Varuna and 50000 Quaoar, large cubewanos.
• 90482 Orcus and 28978 Ixion, large plutinos.
• 90377 Sedna, a distant object, proposed for a new category named Extended scattered disc (E-SDO), detached objects, Distant Detached Objects (DDO) or Scattered-Extended in the formal classification by DES.
• Haumea, a dwarf planet, the fourth largest known trans-Neptunian object. Notable for its two known satellites and unusually short rotation period (3.9 h).
• Eris, a dwarf planet, a scattered disc object, and currently the most massive known trans-Neptunian object. It has one known satellite, Dysnomia.
• Makemake, a dwarf planet, a cubewano, and the third largest known trans-Neptunian object.
• 2004 XR₁₉₀, a scattered disc object following a highly inclined but nearly circular orbit.
• (87269) 2000 OO₆₇ and (148209) 2000 CR₁₀₅, remarkable for their eccentric orbits and large aphelia.
• 2008 KV₄₂, the first retrograde TNO, having an orbital inclination of i = 104°.
