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, ...

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

Typically, telescopes are synonymous with bringing far-off objects close, but the newest member of the solar system was ...

"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 ...

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 ...

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

Scientists have discovered a sednoid, named Ammonite, beyond Neptune. This icy object challenges existing theories about the outer solar system's formation.

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.

The Subaru Telescope has made an exciting discovery: a small body beyond Pluto, with implications for the formation, ...
