Planet Nine
Planet Nine is a hypothetical planet in the outer region of the Solar System . Its gravitational influence could explain a statistical anomaly in the distribution of orbits of a group of distant trans-Neptunian objects (TNOs) found mostly beyond the Kuiper belt in the scattered disc region. [1] [4] [5] This undiscovered super-Earth -sized planet would have an estimated mass of ten Earths, a diameter two to four times that of Earth, and an elongated orbit lasting approximately 15,000 years. [6] [7] To date, efforts to detect Planet Nine have failed. [8] [9]
