After a rigorous analysis and selection process, including visual inspection of images, the team identified one strong candidate pair, where the IRAS and AKARI sources showed the expected angular separation (42′–69.6′) and were not detected at the same position in each survey. The AKARI detection probability map confirmed the candidate’s consistency with a slow-moving object, showing two detections on one date and none six months earlier. However, IRAS and AKARI data alone are insufficient to determine a precise orbit so there will need to be follow-up observations with DECam, which can detect faint moving objects within about an hour of exposure, are suggested to confirm the candidate and fully determine its orbit, aiding in understanding the solar system’s evolution and structure.

The search for Planet Nine continues to push the boundaries of astronomical discovery using advanced survey techniques and paring it with careful analysis. While the identification of a promising candidate is an exciting step forward, confirmation will require further observations and continued collaboration across the astronomical community. If Planet Nine is ultimately detected, it would mark a monumental addition to our understanding of the Solar System.
