I will begin with the historical account of the exploration of the Solar planets beyond Saturn, describe possible intriguing puzzles in the Trans-Neptunian Objects, and introduce the Planet Nine hypothesis to account for their anomalous architecture. This talk is based on a recent excellent review by Konstantin Batygin, Fred C. Adams, Michael E. Brown, and Juliette C. Becker "The planet nine hypothesis" Physics Report 805(2019)1-53, arXiv:1902.10103 https://www.sciencedirect.com/science/article/abs/pii/S037015731930047X |
