Dive into the strange, icy world of dwarf planets, from Ceres, the forgotten inner solar system water world, to the mysterious Sedna lurking near the Oort Cloud. In this video, we uncover the hidden stories behind Pluto's reclassification, the wild tilt of Haumea with its fast spin and asteroid ring, the controversial status of Pluto-Charon as a binary dwarf planet system, and the giant impact theories that shaped these distant celestial objects. Learn why Eris, once thought to dethrone Pluto, still stuns scientists with its high density and methane-rich surface, and how Makemake, with its reddish hue and tiny moon MK2, remains one of the solar system's most elusive bodies. We also explore Orcus, dubbed the "anti-Pluto," and its satellite Vanth, along with the curious rotational behavior and orbit of Gonggong and its moon Xiangliu.

Whether it's cryovolcanoes, salt deposits, or trans-Neptunian objects (TNOs) like Quaoar and 2007 OR10, this deep dive into the Kuiper Belt and beyond will reshape how you think about the outer solar system. From the formation of the solar system and its early collisions to the modern search for Planet 9, this journey through icy orbits, bizarre moons, elliptical paths, and dwarf planet geology is full of surprises. If you’re curious about asteroid belts, perihelion, aphelion, or just why some of these objects spin so weirdly, this is your complete tour of the solar system’s most overlooked residents.
