This how Hermes Asteroids formed. Gas and Dust collect in a nebula. Particles start to join together. Small objects form through accretion. After that the Asteroids start to form. Large objects cant accrete because the gravity of Jupiter and Mars pull at them. Now they exist in an Asteroid Belt of small objects and cant become planets.
Vocab

fussion- when atoms collide and fuse together.
