2013 UH15 is an extreme
extended scattered disc object (ESDO) is on a highly eccentric orbit and belongs to the extreme trans-Neptunian objects
.
Orbit and classification
2013 UH15 orbits the Sun at a distance of 35.0–305
It belongs to a small group of detached objects with perihelion distances of 30 AU or more, and semi-major axes of 150 AU or more.[6] These extreme trans-Neptunian objects (ETNOs) can not reach such orbits without some perturbing object, which lead to the speculation of Planet Nine.
Numbering and naming
As of 2018, this
numbered nor named by the Minor Planet Center. The official discoverers will be defined when the object is numbered.[1]
