HAUMEA FAMILY – A group of Kuiper Belt objects believed to have formed from a collision involving Haumea.
SPHERICAL SHAPE – A condition for dwarf planethood, requiring that gravity shapes the body into a rounded form.
SCATTERED DISK OBJECTS – Bodies in highly eccentric or inclined orbits due to past gravitational encounters.
CLASSICAL KUIPER BELT OBJECTS – Objects with relatively circular orbits and low inclinations beyond Neptune.
RESONANCE ORBITS – Orbital relationships where gravitational interactions with larger planets, like Neptune, affect the orbits of smaller objects.
PLUTINOS – Kuiper Belt objects in a 3:2 resonance with Neptune, like Pluto.
TRANS-NEPTUNIAN OBJECT (TNO) – Any minor planet that orbits the Sun beyond Neptune.
ORBITAL CLEARING – The ability of a planet to dominate and remove other objects in its orbital path—something dwarf planets fail to do.
