       Astronomers theorize that there's a large object in the outer Solar System, influencing the orbits of various Kuiper Belt objects. Dubbed "Planet 9," it hasn't been directly detected yet, but people continue to search for it. In a new paper, researchers looked through two infrared sky surveys and found 13 objects that matched the estimated flux and orbital motion of Planet 9. After more inspections, they were left with a single object. Is this Planet 9?https://arxiv.org/abs/2504.17288
