Planetesimal Theory?

Answer

Planetesimals are solid objects believed to exist in protoplanetary disks and in debris disks. Planetesimals lay a basis to the planetesimal theory that tries to explain the formation of planets through gradual material buildup. The combining of many planetesimals leads to the formation of protopanets.
