Explanation:

The largest two Kuiper Belt objects are Pluto and Eris, with Pluto being slightly larger at a diameter of 2,377 kilometers (1,477 miles). There are between three and seven other known KBOs(Kuiper Belt Objects) with diameters that are approximately 950-1,500 kilometers (600-900 miles), including Pluto's largest moon, Charon. Scientists believe additional KBOs in the 950-2,000 kilometer size range will be found, but most KBOs are much smaller.
