"Unseen Giant Planet Discovered in Our Solar System"

Astronomers are searching for evidence of a ninth planet, dubbed "Planet Nine" or "Planet X," in our Solar System. The discovery of dwarf planets and their unexpected orbits suggests the presence of a large planet at least ten times the mass of Earth. However, locating Planet Nine is challenging due to its distance from the Sun and faintness. New telescopes and sky surveys in the next decade may provide the opportunity to confirm or disprove its existence.
