Science 101: The Solar System
The solar system came into being about 4.5 billion years ago when a cloud of interstellar gas and dust collapsed, resulting in a solar nebula, a swirling disc of material that collided to form the solar system.
Chapter 1: The Solar System
Our whole solar system, along with all the local stars you can see on a clear dark night, reside in one of our galaxy's spiral arms, known as the Orion arm, as they orbit the
