US EditionPlanet Y? Astronomers find fresh clues of hidden world in our solar system
New research infers Planet Y from tilted Kuiper Belt orbits, potentially smaller and closer than Planet Nine, with future data from Rubin Observatory expected to confirm.
- Astronomers propose a new candidate called Planet Y inferred from tilted Kuiper Belt orbits, describing it as smaller and closer to the Sun than Planet Nine.
- After Neptune's discovery, astronomers kept searching for another planet, and Eris's 2005 discovery reshaped views, renewing hypotheses about hidden distant objects.
- The Rubin Observatory's sky survey will directly search for distant outer-Solar-System objects and map their orbits with unprecedented clarity during its decade-long sky survey.
- Researchers say Planet Y represents one of multiple ninth-planet scenarios, and scientists expect more data will clarify if Planet Y alone or additional hidden members exist beyond Neptune.
- In the coming years, Rubin Observatory data should clarify the outer Solar System's structure, with researchers predicting definitive answers within two to three years.

Astronomers have discovered a strange turbulence in distant celestial bodies. Is there a planet behind it that has not yet been discovered?
Scientists are on the trail of a new ninth planet in the solar system, which they have named Y, located in the Kuiper belt region, according to a recent study.
Astronomers uncover a hidden world on the solar system’s edge
Astronomers have uncovered a massive new trans-Neptunian object, 2017 OF201, lurking at the edge of our solar system. With an orbit stretching 25,000 years and a size that may qualify it as a dwarf planet, this mysterious world challenges long-held assumptions about the “empty” space beyond Neptune. Its unusual trajectory sets it apart from other distant bodies and may even cast doubt on the controversial Planet Nine hypothesis.
