This method of looking at orbits and planetary body movements found Neptune after Uranus was discovered:-http://io9.gizmodo.com/5987515/how-astronomers-discovered-planets-hundreds-of-years-ago -Neptune-The last ‘official' planet in our solar system is Neptune. Orbiting 30 AU from the Sun, it's the first planet to have been discovered through mathematics, rather than direct observation. Astronomers studying Uranus found that the planet was deviating from their predictions, and attempted to uncover the problem. The planet's orbit was already known to have been influenced by the other major bodies in the Solar System, but even with the calculations at hand, Uranus was defying expectations. In 1835, Halley's Comet reached its perihelion slightly later than predicted, leading astronomers to believe that there was an additional body in the system that was influencing Uranus.-Astronomers began to look further out for something that would explain the planet's movements. Astronomers in both England and France began to crunch the numbers: John Couch Adams and Urbain Le Verrier. Between 1843 and 1845, Adams worked out the calculations, but was rebuffed by the Royal Astronomical Society. Le Verrier found a similar reception, and turned to Johann Gottfried Galle, who, following Le Verrier's instructions, discovered the new planet exactly where it was predicted to be on September 23rd, 1846. The next month, an English astronomer discovered Neptune's moon Triton. The solar system instantly doubled in size with the discovery. -Comment: Planet 9 seems very possible. The use of planetary geometry is amazing.
