Examples

“This provides a possible explanation for the low fraction of twotinos compared to plutinos in the Kuiper belt.”

“Plutinos are Kuiper belt objects in a 2:3 resonance (a = 39.4 AU) with Neptune and are named after Pluto since these bodies have orbits similar to Pluto. Twotinos are objects that are in a 1:2 resonance (a = 47.8 AU) with Neptune.”

“These objects have been given the name of twotinos (rhymes with "plutinos"). Interestingly, there are very few low-eccentricity TNOs beyond the twotinos.”
