Solar system - Origin, Planets, Formation: As the amount of data on the planets, moons, comets, and asteroids has grown, so too have the problems faced by astronomers in forming theories of the origin of the solar system. In the ancient world, theories of the origin of Earth and the objects seen in the sky were certainly much less constrained by fact.

How and When the Earth and Moon Formed

The Earth formed over 4.6 billion years ago out of a mixture of dust and gas around the young sun. It grew larger thanks to countless collisions between dust particles, asteroids, and other growing planets, including one last giant impact that threw enough rock, gas, and dust into space to form the

OverviewFormation and evolutionGeneral characteristicsSunInner Solar SystemOuter Solar SystemTrans-Neptunian regionMiscellaneous populations

The Solar System formed at least 4.568 billion years ago from the gravitational collapse of a region within a large molecular cloud. This initial cloud was likely several light-years across and probably birthed several stars. As is typical of molecular clouds, this one consisted mostly of hydrogen, with some helium, and small amounts of heavier elements fused by previous generations of stars.

How our solar system was born

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

The Sun Shines The Big Bang brought the Universe into existence 13.8 billion years ago. Our solar system formed much later, about 4.6 billion years ago. It began as a gigantic cloud of dust and gas created by

3.1: Origin of Earth and the Solar System

Our solar system began to form around 5 billion years ago, roughly 8.7 billion years after the Big Bang. A solar system consists of a collection of objects orbiting one or more central stars. All solar systems start out the same way. They begin in a cloud of gas.

The formation of our solar system was a destructive process!

A simplified view of the classical model for terrestrial planet formation (not to scale). From top to bottom: The central star is surrounded by nebular gas and dust where early solids form. In the next stage, nebular gas begins to dissipate over 2–3 million years

The Formation and Evolution of the Solar System

Historical Highlights The first attempts to understand how the planets have born and solar system structured were undertaken in the Middle Ages. In the 16th century, Italian monk, doctor of theology, and author Giordano Bruno voiced against the church dogma that Earth is center of the World, arguing instead for a configuration of the solar system with Earth orbiting the Sun.

How did the Solar System form?

The Solar System[ d ] is the gravitationally bound system of the Sun and the objects that orbit it. [ 11 ] It formed about 4.6 billion years ago when a dense region of a molecular cloud collapsed, forming the Sun and a protoplanetary disc.

When did the Solar System start?

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 ]

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.

What is a basic concept of the origin of the Solar System?

A basic concept of the origin of the solar system. Scheme for the formation of the solar system, from the collapse of a molecular cloud fragment through the formation of the proto-Sun and protoplanetary disk (1,2), followed by its breakup into individual ring clumps of solid particles, eventually giving birth to planetesimals (3,4).

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.

How did planets form?

This idea was then buoyed significantly in the early 1980s when astronomers spotted dusty, flat discs of material located around young stars, called protoplanetary discs or ‘proplyds’. This effectively caught planet formation in the act elsewhere in space. Observing other solar systems is now key to understanding how ours formed.
