Planet 9 from Outer Space

The video discusses the potential existence of a ninth planet in our solar system, based on peculiar orbits of objects in the Kuiper Belt. Researchers from Caltech propose that a planet, ten times the mass of Earth, could explain these orbits. The video outlines the challenges in directly observing this planet due to its distance and dimness, and suggests testing the hypothesis by finding mirror-image asteroids. This method mirrors how Neptune was discovered in the 1840s. The video concludes with a call to support Scishow and subscribe for updates.
