Schematic of a protoplanetary disk cross-section 
from the Far-Infrared Interferometer mission proposal.

This schematic "cartoon" of a protoplanetary disk cross-section is from the Far-Infrared Interferometer (FIRI) ESA mission proposal (see below), which is a good general read about what isn't known and needs to be learned about protoplanetary disks. This broad research topic includes how asteroids, comets, and meteors were formed, as well as the rest of the Solar System and our own selves, of course.
