Formation and evolution of the Solar System - Wikipedia
There is evidence that the formation of the Solar System began about 4.6 billion years ago with the gravitational collapse of a small part of a giant molecular cloud. [1] Most of the collapsing mass collected in the center, forming the Sun , while the rest flattened into a protoplanetary disk out of which the planets , moons , asteroids , and ...

2024年12月5日 · The solar system is a pretty busy place. It’s got all kinds of planets, moons, asteroids, and comets zipping around our Sun. But how did this busy stellar neighborhood come to be? Our story starts about 4.6 billion years ago, with a wispy cloud of stellar dust. This cloud was part of a bigger cloud called a nebula.
Solar System Facts - Science@NASA
Our solar system formed about 4.6 billion years ago from a dense cloud of interstellar gas and dust. The cloud collapsed, possibly due to the shockwave of a nearby exploding star, called a supernova. When this dust cloud collapsed, it formed a …
How our solar system was born - Natural History Museum
Discover how a giant interstellar cloud known as the solar nebula gave birth to our solar system and everything in it. The solar system as we know it began life as a vast, swirling cloud of gas and dust, twisting through the universe without direction or form.

14 Solar System Formation - City University of New York
This illustration shows the steps in the formation of the solar system from the solar nebula. As the nebula shrinks, its rotation causes it to flatten into a disk. Much of the material is concentrated in the hot center, which will ultimately become a star.
