In astronomy, a resonant trans-Neptunian object is a trans-Neptunian object in mean-motion orbital resonance with Neptune. The orbital periods of the resonant objects are in a simple integer relations
The orbital period of 2001 XT254 around the 3:7 resonance (2.333) with Neptune.
The orbital period of 1995 TL8 missing the 3:7 resonance (2.333) with Neptune.
58534 Logos, or as a binary system Logos–Zoe, is a likely trans-Neptunian contact binary or close-binary triple system in the cold classical population of the Kuiper belt. The contact binary is approx
