Summary:
- Astronomers have found evidence that suggests the existence of a large, undiscovered planet in the outer reaches of our solar system, known as "Planet Nine."
- The researchers used computer simulations to analyze the orbits of distant solar system objects and determined that there is a 40% chance that Planet Nine exists, given the right conditions.
- If confirmed, Planet Nine would be the first new planet discovered in our solar system since Uranus was found in 1781, and it could help explain the unusual orbits of some distant objects.
