If you read about the formation of the solar system, you will learn that the planets began as dust grains in orbit around the central protostar.
As they collided with each other, these grains formed into clumps between one and ten kilometres (km) in diameter. These in turn collided to form larger bodies (planetesimals) of about 5 km in size.
And these gradually increased through further collisions to form the planets over the course of the a few million years.
