The stages of the Nebular theory are: 1. Nebula formation - a giant molecular cloud collapses under its own gravity. 2. Disk formation - the nebula flattens into a spinning disk due to conservation of angular momentum. 3. Planetesimal formation - small particles in the disk collide and stick together to form planetesimals. 4. Planet formation - these planetesimals continue to collide and merge to form planets.
