the.com/kuiper belt
A frozen graveyard of leftover planet parts, Neptune's messy backyard.
means A vast, disc-shaped ring of icy bodies and dwarf planets (like Pluto) orbiting the Sun beyond Neptune, made of debris left over from the solar system's formation.
from Named after astronomer Gerard Kuiper, who in 1951 theorized that short-period comets must come from a disc of icy debris beyond Neptune — though the idea had been floated earlier by others like Kenneth Edgeworth, and Kuiper himself actually doubted such a belt still existed in his own time. The region wasn't confirmed observationally until 1992, with the discovery of the first Kuiper Belt Object after Pluto itself. The name stuck to honor his theoretical groundwork, even though the credit is historically a bit tangled.
