context: The zone was first proposed by Frederick C. Leonard in 1930 (at the time of Pluto's discovery) and Kenneth E. Edgeworth in 1943. In 1951, Gerard Kuiper, who named the zone, suggested that there were no more objects left in the zone. More detailed estimates of the existence of the area's sites were made by Al G. W. Cameron in 1962, Fred L. Whipple in 1964 and Julio Fernandez in 1980. [5]
