What materials primarily constitute the icy bodies known as Kuiper Belt Objects (KBOs)?
Answer
Frozen volatiles like methane, ammonia, and water mixed with rock and carbonaceous material
The Kuiper Belt is composed of primordial material that formed beyond the solar system's ice line. The objects here, KBOs, are essentially remnants from the system's birth and are characterized by being rich in frozen volatiles. These volatiles include ices such as methane, ammonia, and water, which are mixed together with rock and carbonaceous compounds, preserving the original chemical conditions of that distant formation zone.
