after our solar system began to form dust and gas combined into small bodies that formed the planets. what are
these small bodies called?

Planetesimals

Explanation:

Planetesimals are a part of a protoplanetary disk that forms around young stars whose planetary systems are just beginning to form. The gravitational consolidating of the disk of dust and gas orbiting the star leads to the formation of small bodies called planetesimals. These planetesimals, in turn, collide with each other and coalesce to eventually form planets that clear the area of their orbit.
