Abstract: The latest addition to the inventory of the solar system is a large population of planetesimals situated beyond Neptune. This population is identified as the Kuiper Belt, a disk-like distribution of icy bodies whose existence was predicted based on cosmogonic considerations. The Kuiper Belt is estimated to contain $\sim$ 70,000 objects with diameters $> 100$ km ($\sim$ 0.06 $M_{\rm Earth}$) in the 30-50 AU zone. This paper summarizes the latest census on the Kuiper Belt population.
