Our Solar System: What’s a Protoplanetary Disk?
We know how the solar system was formed. We also know that the planets grew out of a protoplanetary disk. Protoplanetary disks typically have masses that are only a few percentage of their star’s mass. They are also very thin, with a thickness of only about 10% of their radii. The disks contain gasses, like hydrogen and helium, and also micron-sized dust particles. […]
