Amir Siraj 和他的團隊將這顆可能的新行星命名為 Y 行星，並強調這些天體在經過科學驗證之前都不會被正式命名。

A group of astronomers have identified potential evidence of a hidden planet in our Solar System, referred to as 'Planet Y'.

This Earth-sized world is believed to be located at the very outskirts of the Solar System.

The research introduces the idea of multiple unidentified planets beyond the orbits of Neptune and Pluto.

The latest study, featured in the science journal arXiv, indicates a warping effect observed in the movements of certain Kuiper belt objects, hinting at an undiscovered planet.

Astrophysicist Amir Siraj, leading the investigation on Planet Y at Princeton University, explains how the gravity of this speculated planet could be influencing nearby objects' orbits.

The existence of Planet Y remains theoretical and awaits confirmation through the Vera C. Rubin Observatory's upcoming sky-mapping project.

Another speculated hidden planet, known as Planet X or Planet Nine, is suggested to be significantly larger than Earth, potentially explaining peculiar orbits within the Kuiper Belt.

NASA describes the Kuiper Belt as a zone of frozen debris extending beyond Neptune's orbit.

Amir Siraj and his team have labeled this possible new planet as Planet Y, emphasizing that none of these celestial bodies are officially named until scientific validation.
