A newly discovered dwarf planet called 'Ammonite' (2023 KQ14) has been spotted in the outer solar system, and it could be another nail in the coffin for the Planet Nine hypothesis.
The celestial body's unusual orbit “implies that something extraordinary occurred" in the early days of the solar system—and ...
Japan's Subaru Telescope in Hawaii detected a faint, icy body. Now named 2023 KQ14, or Ammonite, it lies well beyond Pluto.
Astronomers have discovered a new member of a rare and mysterious class of solar system objects known as sednoids - a subset of extreme trans-Neptunian objects (ETNOs) with exceptionally distant, ...
"It is possible that a planet once existed in the solar system but was later ejected, causing the unusual orbits we see today ...
KQ14, nicknamed "Ammonite", was discovered using the Subaru Telescope and is a highly elliptical object with a perihelion and ...
Typically, telescopes are synonymous with bringing far-off objects close, but the newest member of the solar system was discovered using wide-field imaging. The Subaru Telescope has spotted a distant ...
For reference, Pluto’s average distance from the Sun is about 40 AU, so 2023 KQ14 is quite distant. At 23.4 billion miles (37 ...
Learn more about a sednoid called Ammonite that has been detected in the outer reaches of the Solar System. By Rosie McCall . Jul 21, 2025 6:35 PM Jul 21, 2025 6:42 PM (Image Credit: Sergey ...
A tiny object far beyond Pluto, newly discovered by the Subaru Telescope, could reshape our understanding of the early Solar System. Named 2023 KQ14, this rare “sednoid” follows an unusual orbit that ...
The discovery was made by astronomers using the Subaru Telescope, which is situated atop a dormant volcano in Hawaii.
Scientists have previously explained that a sednoid is a trans-Neptunian object (TNO) with a large semi-major axis, a distant perihelion and a highly eccentric orbit.
