The Planet 9 in the Outer Solar System
Introduction Evidence Of A Massive Object Beyond The Orbit Of Neptune and the solar system’s distant reaches exhibit a wealth of anomalous dynamical structure. NASA researchers have found mathematical evidence suggesting there may be a "Planet X" deep in the solar system. The outer reaches of our solar system, beyond the orbit of Neptune, are home to a vast number of trans-Neptunian objects (TNOs). These are generally small, icy bodies that orbit the sun at distances greater than 30 astronomical units (AU), where one AU is the average distance between Earth and the sun. Over 3,000 TNOs have been identified, including dwarf planets like Pluto and Eris, as well as smaller Kuiper Belt objects. These objects are far enough from Neptune that its gravity doesn't significantly affect them; instead, they're mostly tied to the solar system by the distant pull of the sun. Anomalies in the Outer Solar System Interestingly, the orbits of some of these TNOs exhibit anomalous...
