Origin of the Solar System
Early scientific theories The Kant-Laplace nebular hypothesis Kant''s central idea was that the solar system began as a cloud of dispersed particles. He assumed that the mutual gravitational attractions of the particles caused them to start

In what order did the planets in our solar system form?
A cloud of collapsing gas created our Sun, the first thing to form in our solar system. This happened about 4½ billion years ago. Then the planets began to emerge, as the billions of particles of gas and dust left over from the

7.4 Origin of the Solar System
Taken together, the members of the solar system preserve patterns that can tell us about the formation of the entire system. As we begin our exploration of the planets, we want to introduce our modern picture of how the solar system

The nebular hypothesis says that the Solar System formed from the gravitational collapse of a fragment of a giant molecular cloud, most likely at the edge of a Wolf-Rayet bubble. The cloud was about 20 parsecs (pc), or approximately 65 light-years (ly) across, while the fragments were roughly 1 pc (~3.26 ly) across. The further collapse of the fragments led to the formation of dense cores 0.01–

How did the Solar System start?
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. About 4.6 billion years ago, this gigantic cloud was transformed into our Sun. The processes that followed gave rise to the solar system, complete with eight planets, 181 moons, and countless asteroids.
How did the Sun and planets form?
Part of Hall of the Universe. The Sun and the planets formed together, 4.6 billion years ago, from a cloud of gas and dust called the solar nebula. A shock wave from a nearby supernova explosion probably initiated the collapse of the solar nebula. The Sun formed in the center, and the planets formed in a thin disk orbiting around it.
How has the Solar System evolved?
The Solar System has evolved considerably since its initial formation. Many moons have formed from circling discs of gas and dust around their parent planets, while other moons are thought to have formed independently and later to have been captured by their planets. Still others, such as Earth's Moon, may be the result of giant collisions.
Did the Solar System ever form a planet?
And like that, the solar system as we know it today was formed. There are still leftover remains of the early days though. Asteroids in the asteroid belt are the bits and pieces of the early solar system that could never quite form a planet. Way off in the outer reaches of the solar system are comets.
When was Solar System invented?
This concept had been developed for millennia (Aristarchus of Samos had suggested it as early as 250 BC), but was not widely accepted until the end of the 17th century. The first recorded use of the term "Solar System" dates from 1704.
When did ring formation occur in the Solar System?
Although theoretical models indicated that the rings were likely to have formed early in the Solar System's history, data from the Cassini–Huygens spacecraft suggests they formed relatively late. Formation of the Solar System after gas and dust coalesced into a protoplanetary disk.
