The existence of Planet Nine is debated, with arguments suggesting that anomalous orbits of trans-Neptunian objects could be due to past interactions with a passing star rather than an undiscovered planet. Recent studies propose that alternative massive objects in the outer solar system may contribute to these unusual orbits. Future observations, particularly using the advanced Dark Energy Camera, will be crucial in resolving these hypotheses. The conversation also touches on the complexities of planetary objectives and the stability of predicted orbits, indicating ongoing research and exploration in this area.
