What are the theories that explain the formation of the solar system?

Answer 1

The theory is that it all started out as a rotating cloud of gas, ice, and dust particles. Then a shock wave (possibly from an exploding star) caused the cloud to start condensing and spinning faster and faster. The cloud started spinning so fast that ice and dust started smashing into each other with enough force to take gas with it after they colided. This was like a "snowball" effect getting more ice, dust, and gas into larger chunks forming planets, moons, and other objects in our solar system. The disk started taking shape and the planets and moons found different orbital cycles and came to be now what we call our solar system.

This is just one theory, there are many more but this is the only one I know. =P

Laplace's nebula theory (1796):it all began from a huge cloud of gas which was spinning slowly. This cloud collapsed under gravity. As it collapsed, it started spinning more quickly and began to flatten to conserve angular momentum.

Schmidt-Lyttleton accretion theory (1944):Sun passed through a huge cloud of gas and acquired matter to form planets.

Proto-planet Theory:started with a cloud of dust and gas in a state of hypersonic turbulence. Thus, rapid internal collisions took place. This resulted in aggregation of masses at various places

Capture Theory:interaction between a condensed solar mass star (SUN) and a protostar of lesser mass. The protostar entered the Roche limit and was disintegrated to form bodies like planets.

The Solar Nebula Theory:slowly rotating nebula very similar to the Laplacian theory. The planet formation starts with a disc of 0.01 to 0.1 solar masses. This is also a monistic theory dealing with mass and angular momentum distribution.

The Modern Laplacian Theory:started with a cool gas cloud which condensed in such a way that the angular momentum of the central body was only 1 percent of the system.

Answer 2

1. Nebular hypothesis: Current and most accepted. The Solar System formed from the gravitational collapse of a giant molecular cloud.
2. Tidal theory: The planets were formed when another star drew near and "ripped" pieces off of the Sun.
3. Interstellar cloud theory: The Sun passed through a cloud of interstellar gas and dust from which the planets formed.
4. Protoplanet theory: The Sun and planets individually coalesced from matter within the same cloud.
5. Capture theory: The Solar System formed from tidal interactions between the Sun and a low density protostar.
6. God theory: A god or Mythical being, created the Solar System.

Answer 3

The sun formed from a nebula and the leftover materials became planets, moons, ect. Mercury, Venus, Earth, and Mars were made of rock(which are heavy), so the sun's gravity couldn't push it far away. Jupiter, Saturn, Uranus, and Neptune were made of gases(which are light), so the sun's gravity could push it farther away.

Answer 4

One theory is the Exploding Star Theory. The sun's twin star (stars that revolve around each other) exploded, and the matter formed the planets.

Another theory is the Dust Cloud Theory. The sun and planets formed from large dust and gas clouds that contracted and extra dust and gas were pushed to the edge of the solar system. There are gas and dust clouds in space.

A different version of the Dust Cloud Theory is that a nebula collapsed and gravity squeezed the particles together. They rotated faster and faster. Then, in nuclear reactions, hydrogen atoms changed into helium gases, were very hot, and became the sun. The particles combined and became the planets.

The Dust Cloud Theory is the most likely theory about how our solar system formed.

Answer 5

The two main theories that explain the formation of the solar system are the nebular hypothesis and the disk instability model. The nebular hypothesis suggests that the solar system formed from a rotating disk of gas and dust around the young Sun, while the disk instability model proposes that gravitational instabilities in the disk led to the formation of clumps that eventually became planets.

Answer 6

One of the theories about the origin of the solar system is the nebular hypothesis. The most accepted theory is the big band theory.
