👉 A protoplanet is a type of planet that formed from gas and dust in a very young stage of its formation. It is an intermediate stage between the main planets, Jupiter and Saturn, and is characterized by a thin atmosphere, a rocky crust, and a small moon or ring system. Protoplanets are thought to be remnants of a larger planetary system that has been torn apart due to gravitational collapse, such as the Solar System in our solar system.
