Orbit and classification
Neptune trojans can be considered resonant trans-Neptunian objects in a Resonant trans-Neptunian object#1:1, 1:1 mean-motion orbital resonance with Neptune. These Trojan (astronomy), trojans have a semi-major axis and an orbital period very similar to Neptune's (30.10 AU; 164.8 years). belongs to the leading group, which orbits 60Degree (angle), ° ahead of Neptune's orbit. It orbits the Sun with a semi-major axis of 29.926 Astronomical unit, AU at a distance of 28.1–31.7 AU once every 163 years and 9 months (59,795 days). Its orbit has an orbital eccentricity, eccentricity of 0.06 and an orbital inclination, inclination of 28Degree (angle), ° with respect to the ecliptic. Its inclination is almost as high as that of .Physical characteristics
Diameter
The discoverers estimate that has a mean-diameter of 160 kilometers based on a Magnitude (astronomy), magnitude of 22.2. Based on a generic magnitude-to-diameter conversion, it measures approximately 110 kilometers in diameter using an absolute magnitude of 7.9 with an assumed Astronomical albedo, albedo of 0.10.Numbering and naming
This minor planet was numbered by the Minor Planet Center on 18 May 2019 (). As of 2019, it has not been named. If named, it will follow the naming scheme already established with 385571 Otrera and 385695 Clete, which is to name these objects after figures related to the Amazons, an all-female warrior tribe that fought in the Trojan War on the side of the Trojans against the Greek.References
