plutino

Etymology
From, meaning "little Pluto" (compare ); coined by , et al.

Noun

 * 1)  Any planetoid in the Kuiper belt whose orbit, like that of Pluto, has a resonance of 3:2 with that of Neptune.

Usage notes

 * Other resonances are possible, but the 3:2 resonance, being of low order, is the strongest and most stable, and consequently corresponds to the largest such grouping of Kuiper belt planetoids.
 * Saying that an object's orbit has the same resonance with Neptune's as Pluto's orbit does is the same as saying that the average distance from the sun is the same as Pluto's (within a margin of error).
