2016 NY 210 and 2025 EA 16 : Two Possible Dwarf Planets Discovered by Visual Blinking
Year: 2026
Type: article
Abstract: In the era of automated minor planet search pipelines, I present two trans-Neptunian objects (TNOs), 2016 NY 210 and 2025 EA 16 , that remained hidden in archival Dark Energy Camera (DECam) images until they were found by the old-fashioned method of visual blinking. Both have orbits within the range of the main classical Kuiper Belt, with inclinations of 22 . ° 7 and 13 . ° 5 . Their absolute magnitudes ( H = 4.34 and 4.55) imply diameters of several hundred kilometers for plausible albedos, which could place them among the dwarf-planet candidates. These sizes are estimates. To my knowledge, their physical properties have not been measured, so I invite photometry and astrometric follow-up.
