Astronomers discovered 2023 KQ14, nicknamed Ammonite, a sednoid located far beyond Pluto. It is about 71 times farther from the sun than Earth. This object follows a unique, stable orbit for approximately 4.5 billion years. Once considered similar to other sednoids, its orbit has changed over time, suggesting greater complexity in the outer solar system. This finding also raises doubts about 'Planet Nine,' as 2023 KQ14's orbit does not align with predicted positions of such a planet. Researchers suggest a planet may have existed and been ejected from the solar system, affecting current orbits.
Astronomers discovered a new world named Ammonite, classified as a sednoid, located far beyond Pluto at about 71 times the Earth-sun distance.
2023 KQ14 has a unique, stretched-out orbit that has remained stable for approximately 4.5 billion years, similar to other sednoids but changed over time.
The discovery of 2023 KQ14 suggests the outer solar system is more complex than previously thought and makes the existence of 'Planet Nine' less likely.
Dr. Yukun Huang stated that a planet may have once existed in the solar system but could have been ejected, influencing the unusual orbits observed.
