Searching for Planet Nine

Scientists are examining data that may point to the existence of a ninth planet in our solar system. Researchers have nicknamed the object, which could have a mass of about 10 times that of earth and orbit about 20 times farther from the sun on average than Neptune, “Planet Nine.” It may take between 10,000 and 20,000 Earth years for Planet Nine to make one full orbit around the sun. It’s an exciting possibility, but much more work must be done in order to either prove or disprove this hypothesis.
