Could We Spot It Soon?
Right now, Planet Nine remains a theory. But new tools are being developed that could change that. The Vera C. Rubin Observatory, scheduled to begin full operations soon, will scan the night sky with unprecedented detail and frequency. It is designed to spot moving objects across a wide field of view, making it a powerful tool in the search.
Infrared telescopes, like the James Webb Space Telescope and others on Earth, could also help. Even though Planet Nine would be cold and dim, it might emit a small amount of heat that shows up in infrared images.
Every new observation narrows down the possibilities. If the planet exists, it may only be a matter of time before we find it.
