Astronomers have discovered a possible new dwarf planet orbiting far beyond Pluto. First detected in March 2023 by Japan's Subaru Telescope in Hawaii, this object has been dubbed 2023 KQ14 and ...

Japan's Subaru Telescope in Hawaii detected a faint, icy body. Now named 2023 KQ14, or Ammonite, it lies well beyond Pluto.

The celestial body's unusual orbit “implies that something extraordinary occurred" in the early days of the solar system—and ...

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 ...

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 ...

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 ...

The discovery was made by astronomers using the Subaru Telescope, which is situated atop a dormant volcano in Hawaii.

The sednoid 2023 KQ14, nicknamed "Ammonite", was discovered using the Subaru Telescope and is a highly elliptical object with a perihelion and aphelion that places it beyond the heliopause, ...

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 ...

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.

Astronomers discovered the first Sednoid, named Sedna, in 2003. This animation shows the motion of Ammonite over several hours. Credit: NAOJ/ASIAA.
