English
Etymology
Noun
twotino (plural twotinos)
- (astronomy) Any astronomical object, on the apparent outer edge of the Kuiper Belt, whose orbit has a 1:2 resonance with the planet Neptune.
- 2009, A. C. Quillen, “Resonances in Galactic and Circumstellar Disks”, in G. Contopoulos, P. A. Patsis, editors, Chaos in Astronomy: Conference 2007, Springer, page 199:
- This provides a possible explanation for the low fraction of twotinos compared to plutinos in the Kuiper belt.
- 2017, Thomas H. Burbine, Asteroids, Cambridge University Press, page 234:
- 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.
- 2021, Barbara Ryden, Bradley M. Peterson, Foundations of Astrophysics, Cambridge University Press, page 276:
- These objects have been given the name of twotinos (rhymes with "plutinos").
Interestingly, there are very few low-eccentricity TNOs beyond the twotinos.
