Analysis of the Trans-Neptunian Object 2002 KX14 Using Six Stellar Occultations and Ground-Based Long- and Short-Term Photometry

The Trans-Neptunian Object (TNO) provisionally designated 2002 KX₁₄ has orbital characteristics placing it near the boundary between the cold and hot classical populations. To date, there are very few published measurements of the projected shapes and sizes of TNOs, resulting in limited knowledge of their true three-dimensional forms and the orientations of their spin axes. In this study, we present results based on six stellar occultations, five of them recently presented in Rizos et al. (2025), supplemented with new measurements and a reanalysis of existing data. Our findings suggest that 2002 KX₁₄ is consistent with an oblate body, with a major axis of 460 ± 6 km and a minor axis of 337 ± 10 km. This corresponds to a projected-area equivalent diameter of 385 ± 8 km. This value is smaller than the diameter estimated from thermal observations, though it remains uncertain whether this discrepancy could be attributed to the presence of an undetected satellite. We also provide updated estimates of the geometric albedo and present an analysis of recent photometric observations of the object.
