Astronomers find evidence for a ninth planet

Astronomers may have found evidence suggesting the existence of a ninth planet in our solar system, potentially reclassifying the system after Pluto's demotion. Researchers analyzed data from infrared surveys, finding a celestial object with slight movement, indicating an orbit around the sun. This potential planet is estimated to be Neptune-sized and take 10,000 to 20,000 years to complete an orbit. The evidence includes the unusual clustering of icy bodies in the Kuiper Belt and the object's faint sunlight reflection. Further observations are needed to confirm the planet's orbit and definitively prove its existence.
