What does the word protoplanetary mean?

What is protoplanetary hypothesis?

The leading theory is something known as the “protoplanet hypothesis”, which essentially says that very small objects stuck to each other and grew bigger and bigger — big enough to even form the gas giants, such as Jupiter.

As the central body, or protostar, of the system contracts and heats up, the increasing pressure of its radiation is believed to drive off much…

What causes the protoplanet to move away from the star?

As the central body, or protostar, of the system contracts and heats up, the increasing pressure of its radiation is believed to drive off much of the thinner material of the protoplanets, particularly those closer to the nascent star.
