US EditionJapan Discovers Object Beyond Pluto, Puts Planet 9 in Doubt
OUTER SOLAR SYSTEM BEYOND PLUTO, JUL 21 – Ammonite is the fourth known sednoid with an orbit unlike others, weakening the Planet Nine theory and suggesting a stable orbit for 4.5 billion years, researchers said.
- Japan's National Astronomical Observatory discovered a small celestial body named 2023 KQ14 beyond Pluto using the Subaru Telescope in 2023.
- Scientists found 2023 KQ14 has a stable, unusual orbit differing from other sednoids, challenging the Planet Nine hypothesis and implying an extraordinary ancient event.
- Follow-Up observations over 19 years, including those by the Canada-France-Hawaii Telescope in July 2024, confirmed 2023 KQ14's classification as the fourth known sednoid.
- Dr. Yukun Huang stated that 2023 KQ14’s orbit does not align with other sednoids, which lowers the likelihood of Planet Nine's existence, while Dr. Fumi Yoshida highlighted Neptune's limited influence on its orbit.
- This discovery suggests the outer Solar System's complexity exceeds previous models and calls for revisiting the formation history and the Planet Nine theory.

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 [...]
