Final answer:
The solar system originated from a rotating cloud of vapor and dust called the solar nebula, according to the nebular hypothesis. As this cloud collapsed, material fell towards the center, forming planets and other bodies.
Step-by-step explanation:
The solar system originated according to the nebular hypothesis, which suggests that it formed from a rotating cloud of vapor and dust known as the solar nebula. This cloud had an initial composition similar to that of the Sun today. As the solar nebula collapsed under its own gravity, material fell toward the center, becoming more concentrated and hot. Increasing temperatures in the shrinking nebula vaporized most of the solid material that was originally present. The remaining material coalesced to form planetesimals, which eventually formed the planets and other bodies in our solar system.
