The solar system might have a ninth planet. It is hiding far beyond Neptune. Scientists have been looking for it for years. They have not seen it yet. The evidence comes from strange orbits of small, icy bodies. These orbits suggest a large planet is pulling them with its gravity.

A powerful telescope is almost ready. It is in Chile. The Vera C. Rubin Observatory will start working soon. It is designed to find faint objects in the sky. It will take pictures of the southern sky every night. A giant camera will capture these images. Computers will compare new pictures with old ones. This will help spot any moving objects, like the hidden planet.

The telescope is a big deal for the planet hunt. It is the best chance to find it in the next few years. But there are uncertainties. The planet's size, brightness, and distance are unknown. These factors affect how easy it is to spot. If the planet is small, dark, and far, the telescope might miss it.

Even if the telescope does not find the planet, it will still help. It might find smaller planets. Their orbits could show the hidden planet's influence. This would be more evidence that the ninth planet exists. Right now, the evidence is not strong enough to say for sure.

Some scientists are confident the planet is there. They have seen clues in the solar system's behavior. Others are not so sure. They need more proof. The telescope will provide that proof. It will either find the planet or show that the clues are wrong. Either way, it will be a big step forward.
