A degree (in full, a degree of arc, arc degree, or arcdegree), usually denoted by ° (the degree symbol), is a measurement of plane angle, representing of a full rotation.
Julian day is the continuous count of days since the beginning of the Julian Period used primarily by astronomers.

In astronomy, a Julian year (symbol: a) is a unit of measurement of time defined as exactly 365.25 days of SI seconds each.
In astronomy, libration is a perceived oscillating motion of orbiting bodies relative to each other, notably including the motion of the Moon relative to Earth, or of trojan asteroids relative to planets.

It is estimated that there may be 200 dwarf planets in the Kuiper belt of the outer Solar System and up to 10,000 in the region beyond.
A minor-planet moon is an astronomical object that orbits a minor planet as its natural satellite.
Neptune is the eighth and farthest planet from the Sun in the Solar System.

Observation arc is a term used in observational astronomy, most particularly in discovery and tracking of asteroids and comets.
In celestial mechanics, an orbital resonance occurs when two orbiting bodies exert a regular, periodic gravitational influence on each other, usually due to their orbital periods being related by a ratio of two small integers.
Palomar Observatory is an astronomical observatory located in San Diego County, California, United States, southeast of Los Angeles, California, in the Palomar Mountain Range.
In astronomy, a resonant trans-Neptunian object is a trans-Neptunian object (TNO) in mean-motion orbital resonance with Neptune.
The uncertainty parameter (U) is an integer between 0 and 9 that quantifies the uncertainty in a perturbed orbital solution for a minor planet in a concise fashion, the Minor Planet Center (MPC) has introduced the U parameter.
