Summary:
- The article discusses a new study that has found evidence of a potential ninth planet in our solar system, nicknamed "Planet Nine."
- The study, published in the Astronomical Journal, provides further observational evidence for the existence of this hypothetical planet, which is estimated to be about 10 times the mass of Earth and have an elongated orbit around the Sun.
- The researchers used data from various astronomical surveys and observations to analyze the orbits of distant solar system objects, which appear to be influenced by the gravitational pull of an unseen massive object, potentially Planet Nine.
