Japan Discovers Object Beyond Pluto, Puts Planet 9 in Doubt
OUTER SOLAR SYSTEM, JUL 21 – Ammonite's stable 4.5-billion-year orbit differs from other Sednoids, reducing the likelihood of Planet Nine's existence, researchers say.
- Japan's National Astronomical Observatory discovered a small distant body named 2023 KQ14 beyond Pluto using the Subaru Telescope in 2023.
- Scientists revealed that 2023 KQ14 orbits far from Neptune's gravity and does not align with other sednoids, challenging the likelihood of Planet Nine.
- Follow-Up observations tracked 2023 KQ14's orbit over 19 years, classifying it as the fourth known sednoid with a stable orbit possibly older than 4.5 billion years.
- Dr. Yukun Huang emphasized that studying how these rare, far-flung objects change over time and their characteristics is essential to gaining a complete understanding of the Solar System’s history.
- This finding indicates that the distant regions of the Solar System are more intricate than previously thought and may necessitate updating existing theories about Planet Nine and the early development of remote celestial bodies.

New object flying in our solar system? ASU explains
SAN ANGELO, Texas (Concho Valley Homepage) — Angelo State University's (ASU) Department of Physics and Geosciences explains the new object in our solar system that was announced on July 15 and designated as sednoid 2023 KQ14, nicknamed “Ammonite." After the news broke, CVHP reached out to the ASU's Department of Physics & Geosciences to find out more information about the sednoid designated as 2023 KQ14. What is a sednoid? According to Kenneth C…
‘Ammonite’: A Mysterious Deep Space Fossil That Could Rewrite Solar System History
A mysterious icy object discovered far beyond Pluto is rewriting what we thought we knew about the Solar System’s past. Nicknamed “Ammonite,” this ancient world has an orbit unlike any other, placing it in the ultra-rare class of “sednoids.” Its discovery, made by the Subaru Telescope and confirmed through years of orbital data, challenges theories [...]
