The solar system is very difficult to understand without Planet Nine,” study co-author Mike Brown from Caltech told Universe Today. “Planet Nine explains many things about orbits of objects in the outer solar system that would be otherwise unexplainable and would each need some sort of separate explanation,” Dr Brown said. New data, published in a yet-to-be peer-reviewed study, suggests that planet nine, if it exists, is likely to be the fifth largest planet in the Solar System. However, researchers add caution that there’s a possibility of a ninth planet not existing, raising the need for new theories to explain multiple phenomena observed in the outer Solar System.
