These bodies are believed to carry clues about the early days of the solar system. \u201cAmmonite was found in a region far away where Neptune\u2019s gravity has little influence,\u201d said Dr. Fumi Yoshida, leader of the FOSSIL project. \u201cThe presence of objects with elongated orbits and large perihelion distances in this area implies that something extraordinary occurred during the ancient era when Ammonite formed.\u201d<\/p>\n\n\n\n<p>Researchers compiled&nbsp;<strong>19 years of data<\/strong>, tracing Ammonite\u2019s orbit back to sightings as early as&nbsp;<strong>2005<\/strong>.
