A 2024 article from Phys.org highlights fresh evidence that could support the existence of Planet 9. Researchers have been studying the orbits of distant objects in the Kuiper Belt and have observed that their unusual alignment might be due to the gravitational pull of a massive, yet undetected planet. This hypothetical Planet 9 is estimated to be about 10 times more massive than Earth and follows a highly elongated orbit, making it challenging to detect with current technology. Although direct evidence is still lacking, scientists are optimistic that advanced telescopes now in use might soon confirm the existence of this mysterious planet.
