The video explores why Pluto is no longer considered a major planet by comparing it to the story of Ceres, once thought to be a planet but later reclassified as an asteroid. The discovery of many small celestial bodies between Mars and Jupiter led to the creation of the asteroid belt. Similarly, Pluto is part of the Kuiper Belt, a region with many small, icy bodies. This reclassification helps us understand the structure of our solar system better. The video concludes with a preview of topics for the next episode.
