Plutino

In astronomy, the plutinos are a dynamical group of trans-Neptunian objects that orbit in 2:3 mean-motion resonance with Neptune.

They are also the most populous known class of resonant trans-Neptunian objects (also see adjunct box with hierarchical listing).

It is thought that the objects that are currently in mean orbital resonances with Neptune initially followed a variety of independent heliocentric paths.

As Neptune migrated outward early in the Solar System's history (see origins of the Kuiper belt), the bodies it approached would have been scattered; during this process, some of them would have been captured into resonances.

[5] Numerical simulations suggest that the orbits of plutinos with an eccentricity 10%–30% smaller or larger than that of Pluto are not stable over Ga timescales.
