Astronomers have discovered a rare object in the outer solar system, nicknamed 'Ammonite' and officially designated 2023 KQ14, which is moving in an unexpected synchronized orbit with Neptune, the eighth planet. This sednoid object was identified using the Subaru telescope and is considered an ancient 'fossil' that challenges existing theories about the solar system's formation. The discovery of Ammonite has prompted scientists to reconsider models of planetary development and the dynamics of distant solar system bodies. Its unique orbital relationship with Neptune adds complexity to the ongoing search for the hypothesized Planet Nine and provides new insights into the solar system's structure and history.
