Journey Through the Outer Solar System: Chemistry and Composition Insights

The video explores the outer Solar System, starting with its boundary at Neptune and extending to the Oort Cloud. It discusses the chemistry of the outer Solar System, highlighting the presence of rocks, ice, and hydrocarbons. The Kuiper Belt is introduced as a region filled with icy bodies and comets, with Pluto as a notable object. The hypothetical Planet Nine is discussed, along with its potential orbit and mass. The heliosphere is described as a vast bubble created by the solar wind, and the Oort Cloud is presented as a distant spherical shell of comets. The video concludes with a call to action for viewers to engage with the content.
