Etymology
From Plut(o) + -ino (“diminutive suffix”), meaning "little Pluto" (compare neutrino); coined by David C. Jewitt, et al.
Meanings
-
Any planetoid in the Kuiper belt whose orbit, like that of Pluto, has a resonance of 3:2 with that of Neptune.
This is dubbed a 3:2 resonance (with Neptune), Pluto being the largest Plutino. About one fourth of the KBOs are Plutinos. Plutinos may be debris from the collision of another KBO with Pluto, resulting in the formation of Pluto's largest moon, Charon.
2018, C Sivaram, Kenath Arun, Kiren O V, Current Trends in Astrobiology, Cambridge Scholars Publishing, page 39:We present a study of the dynamical evolution of plutinos recently escaped from the resonance through numerical simulations. It was shown in previous works the existence of weakly chaotic orbits in the plutino population that diffuse very slowly finally diving into a strong chaotic region.
