Icy Pebbles
Theories have long proposed that icy pebbles forming in the cold, outer regions of protoplanetary disks – the same area where comets originate in our solar system – should be the fundamental seeds of planet formation. The main requirement of these theories is that pebbles should drift inward toward the star due to friction in the gaseous disk, delivering both solids and water to planets.
