Circumplanetary Disk

+A **circumplanetary disk** is a rotating band of gas, dust, and planetesimals orbiting a forming [planet](/wiki/planet) or giant [exoplanet](/wiki/exoplanet). Within these cosmic nurseries, a growing world gathers its mass, and its moons may begin to coalesce. They are essential structures emerging from a larger [protoplanetary disk](/wiki/protoplanetary_disk).
