Enigmatic Alien World Discovered in Our Solar System’s Cosmic Backyard
Astronomers Discover Ancient "Fossil" in Outer Solar System

Researchers using Hawaii’s Subaru Telescope have identified a distant object, 2023 KQ14, nicknamed Ammonite, orbiting beyond Pluto. This icy body belongs to a rare class called sednoids—small, ancient relics from the solar system’s infancy. Only four sednoids are known, with Ammonite residing 71 times farther from the Sun than Earth.
A Cosmic Fossil With a Mysterious Past
Ammonite’s elongated orbit has remained stable for 4.5 billion years, but recent shifts in its path suggest the outer solar system’s history is more complex than previously thought. Dr. Yukun Huang, part of the discovery team, speculates a lost planet might have influenced these orbits before being ejected. Planetary scientist Fumi Yoshida adds that Ammonite’s existence implies "something extraordinary occurred during the ancient era" of solar system formation.

Challenging the "Planet Nine" Hypothesis
Ammonite’s discovery weakens the case for Planet Nine, a hypothetical giant planet believed to lurk in the solar system’s outskirts. While earlier studies narrowed potential Planet Nine candidates, Ammonite’s orbit doesn’t align with predictions. If Planet Nine exists, it would need to be even farther away than theorized, raising doubts about its role in shaping outer solar system objects.
Clues From the Kuiper Belt
Sednoids like Ammonite occupy the Kuiper Belt, a region of icy debris beyond Neptune. Their tilted, clustered orbits have long puzzled scientists. Planet Nine was proposed to explain these anomalies, but Ammonite’s unique trajectory suggests alternative forces—like a vanished planet or ancient gravitational tug-of-war—might be at play.

The FOSSIL Survey’s Role
Ammonite was discovered via the FOSSIL survey, which hunts "icy fossils" preserving clues about the solar system’s evolution. Yoshida hopes this finding inspires more discoveries: "A complete picture of solar system history is within reach."
While the search for Planet Nine continues, Ammonite offers a snapshot of our cosmic backyard’s turbulent beginnings—a reminder that even 4.5 billion years later, mysteries still linger.
