What type of celestial bodies are predominantly found in the Kuiper Belt?

In the Kuiper Belt, which lies beyond the orbit of Neptune, the predominant celestial bodies are icy objects. This region is home to a variety of small, icy bodies known as trans-Neptunian objects (TNOs), which include comets, dwarf planets like Pluto, and other similar celestial bodies. These objects are primarily composed of volatile substances such as water ice, ammonia, and methane, which contribute to their classification as icy bodies.

The formation of the Kuiper Belt likely occurred early in the solar system's history, where conditions were favorable for the accumulation of ices. The presence of these icy materials distinguishes the Kuiper Belt from other regions of the solar system, such as the asteroid belt, which primarily consists of rocky and metallic bodies. The icy composition of these objects also allows for significant physical changes when they approach the sun, leading to the formation of comas and tails in the case of comets.

In summary, the significant presence of icy objects in the Kuiper Belt is key to understanding the characteristics and composition of this region. The other options mentioned do not correctly represent the composition and nature of the celestial bodies found in the Kuiper Belt.
