Astronomers using the Subaru Telescope have discovered a new object in the Kuiper Belt, beyond the orbit of Pluto. Designated 2023 KQ14, it's categorized as a "sednoid," with an extremely eccentric orbit - only the 4th ever discovered. Its orbit is much different from other sednoids, which challenges the hypothesis that Planet Nine could be aligning their orbits. It was found at 72 AU, but its path takes it all the way out to 438 AU, taking almost 4,000 years to complete one orbit.
