Kuiper Belt objects are small, icy bodies located in the outer solar system beyond the orbit of Neptune. They are composed mostly of frozen gases, such as methane, ammonia, and water, and can range in size from a few kilometers to hundreds of kilometers across. Kuiper Belt objects are thought to be remnants of the solar system’s early formation, and they provide valuable insights into the conditions that existed during that time.
One of the most interesting Kuiper Belt objects is (50000) Quaoar. Quaoar is a large, icy body that was discovered in 2002. It is about 1,100 kilometers in diameter, making it one of the largest known Kuiper Belt objects. Quaoar is also unusual in that it has a moon, which was discovered in 2007. The moon is about 120 kilometers in diameter and is named Weywot.
