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 ...

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 ...

Researchers just got a step closer to understanding the origins of our solar system, with the discovery of an object orbiting ...

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

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

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 ...
