It was discovered on September 16, 1998, by Nichole Danzl. It is in a 1:2 orbital resonance with the planet Neptune. == Twotino ==
has a semi-major axis (average distance from the Sun) near the edge of the classical belt. Both the Minor Planet Center (MPC) and the Deep Ecliptic Survey (DES) list this trans-Neptunian object as a twotino.〔〔 For every one orbit that a twotino makes, Neptune orbits twice.
