Does planet 9 exit or not?

 "Could Planet 9 Be Real? New Telescope Promises to Provide Answers"

The search for Planet Nine, a mysterious world beyond Neptune, is intensifying as scientists prepare to use a powerful new telescope. 

For years, astronomers have wondered if there is a hidden "Planet Nine" in the farthest reaches of our solar system. It’s thought to be a large planet, several times the mass of Earth, orbiting the Sun far beyond Neptune. This planet is believed to have an orbit so long that it could take anywhere between 10,000 to 20,000 years to complete one trip around the Sun. Though Planet Nine hasn’t been seen directly, some scientists believe its gravity may explain unusual patterns in the orbits of objects in the Kuiper Belt, a region filled with icy bodies past Neptune.

However, the existence of Planet Nine remains uncertain. Some astronomers are convinced it's out there, but others remain skeptical because no one has directly observed it. Various telescopes have been used to search for it, but none have found solid proof. That could soon change with the Vera C. Rubin Observatory, an advanced telescope set to start operating in Chile in late 2025. This new telescope will scan the entire sky every few days, making it the best tool yet to either confirm or rule out the existence of Planet Nine.

If the planet is found, it would be a major breakthrough, changing how we think about the solar system and the formation of planets. But if no evidence is found, it could force scientists to rethink current theories about the objects in the outer solar system. Either way, the upcoming observations will bring us closer to solving one of the biggest mysteries in space.
