Astronomers find evidence suggesting a ninth planet exists

Astronomers suggest a Neptune-sized planet, potentially the ninth in our solar system, may exist far beyond Neptune, challenging Pluto's demotion. Researchers found evidence of this "Planet Nine" in photos from 1983 and 2006, analyzing movement after removing known objects. The planet's orbit could take 10,000 years, according to estimates. While the findings are exciting, some experts remain skeptical, awaiting further confirmation from the Vera C. Rubin Observatory later this year.
