According to this theory, the Sun and all the planets of our Solar System began as a giant cloud of molecular gas and dust. Then, about 4.57 billion years ago, something happened that caused the cloud to collapse. This could have been the result of a passing star, or shock waves from a supernova, but the end result was a.
The idea that the Solar System originated from a nebula was first proposed in 1734 by Swedish scientist and theologian Emanual Swedenborg. Immanuel Kant, who was familiar with Swedenborg’s work, developed the theory.
Although the nebular theory is widely accepted, there are still problems with it that astronomers have not been able to resolve. For example, there is the problem of tilted axes. According to the nebular theory, all planets around.

Some elements of the original nebular theory are echoed in modern theories of planetary formation, but most elements have been superseded. According to the nebular theory, stars form in massive and dense clouds of molecular hydrogen — giant molecular clouds (GMC).
¥The nebular theory holds that our Solar System formed out of a nebula which collapsed under its own gravity. ¥ observational evidence ÐWe observe stars in the process of forming today. Ð The are always found within interstellar clouds of gas. newly born stars in the Orion Nebula Solar Nebula The cloud of gas from which our own Solar System
Proto-Earth Formed. Studies of meteorites and samples from the Moon suggest that the Sun and our Solar System (including proto-planets) condensed and formed in a nebula before or about 4.56 billion years ago. A recent Scientific American article places the current assumed age of the Earth is about 4.56 billion years old. Currently, the oldest samples of Early
Comets condensed in the outer solar system, and many of them were thrown out to great distances by close gravitational encounters with the giant planets. After the Sun ignited, a strong solar wind cleared the system of gas and dust. The asteroids represent the rocky debris that remained. Size and Time Scales of the Solar System
The purpose of this case study is to present our best scientific understanding of the formation of our solar system from a presolar nebula, and to put that nebula in context too. The prevailing scientific explanation for the origin of the Earth does a good job of not only explaining the Earth''s formation, but the Sun and all the other planets too.

Scientists describe the overall formation of a solar system in what is called nebular theory. Essentially, nebular theory describes the forces and processes at play as a nebular spins, accretes
In the next section, we describe the solar nebular theory for how our solar system formed, and explain how each of the constraints described above are successfully explained by this theory. The cloud of gas and dust that collapsed to became our solar system is called the solar nebula.
6.5.1 Nebular Theory; 6.5.2 Formation of the Planets; From that, we can develop a model to describe how it may have gotten that way. Any model for the origin of the Solar System must be consistent with the laws of physics as first described by Isaac Newton and later expanded by Albert Einstein with his theory of general and special
The nebular theory is a modification of the nebular hypothesis which said that the solar system formed from the gravitational collapse of an interstellar cloud of gas. It is so widely accepted because it offers natural explanations for all four general features of our solar system.
Formation of Solar Systems Solar Nebular Theory. Cloud Collapse: Formation of Protoplanetary disk: Growth of planets: Observational Clues. When the solar system is finally formed and dust has cleared, remnants of the formation process and outlying material in the solar systems (such as "Kuiper belt objects" and "Oort clouds") can be found
3 · A cloud of gas and dust in space is called a "nebula". The Nebular Theory is the scientific theory for how stars and planets form from molecular clouds and their own gravity.
The nebular hypothesis says that the Solar System formed from the gravitational collapse of a fragment of a giant molecular cloud. [12] The cloud was about 20 parsec (65 light years) across, [ 12 ] while the fragments were roughly 1 parsec (three and a quarter light-years ) across.
4 · 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
This action is not available. Our solar system formed at the same time as our Sun as described in the nebular hypothesis. The nebular hypothesis is the idea that a spinning cloud of dust made of mostly light elements, called a nebula, flattened into a protoplanetary disk, and became a solar system consisting of a star with orbiting planets .

Formation of the Solar System Nebular-Condensation theory. Our solar system formed about 4.6 billion years ago. Nebular Theory: Our solar system evolved from a contracting nebula. Under the influence of its own gravity, the nebula contracts. As it contracts, it spins faster and faster, much like an ice skater who pulls in her arms.

The nebular hypothesis is the most widely accepted model in the field of cosmogony to explain the formation and evolution of the Solar System (as well as other planetary systems). It suggests the Solar System is formed from gas and dust orbiting the Sun which clumped up together to form the planets. The theory was developed by Immanuel Kant and published in his Universal Natural History and Theory of the Heavens
The nebular hypothesis is the most widely accepted model for the formation of our Solar System. It explains how all of the planets formed in their current orbits, and why they are made of different materials. How the Solar System Was Formed? The solar system was formed as a result of the gravitational collapse of a gaseous nebula.

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 (65 light years) across, while the fragments were roughly 1 parsec (three and a quarter light-years) across. The further collapse of the fragments led to the formation of dense cor
Answer: Holds that the solar system formed from the gravitational collapse of a great cloud of gas and dust, successfully explains all the major features of our solar system. The nebular theory of solar system formation gained wide acceptance because of its success in explaining the major characteristics of our solar system.
Describe the motion, chemical, and age constraints that must be met by any theory of solar system formation; where orbits were slow, the nebular material fell directly into the center. Faster moving material, on the other hand, collapsed into a flat disk revolving around the central object (Figure (PageIndex{1})).
The most widely accepted view about the formation of the solar system is the Nebular Hypothesis proposed by Laplace. It has the following key points-1. A rotating nebula (cloud of dust and gas) forms from a collapsing interstellar gas cloud. we discussed about the Solar System Formation and the Nebular theory proposed by Laplace, how it
Describe the motion, chemical, and age constraints that must be met by any theory of solar system formation; where orbits were slow, the nebular material fell directly into the center. Faster moving material, on the other hand, collapsed into a flat disk revolving around the central object (Figure (PageIndex{1})).
1) The solar system begins as a cloud of dust and gas (nebula) 2) Nebula rotates and collapses toward the center of the cloud 3) Heat and pressure is generated at the center forming the Sun 4) A disk of gas and dust spins around the Sun and particles clump together to form planets (Protoplanetary Disk) 5) Repeated collisions of these particles result in asteroid-sized bodies
The solar nebula model describes formation of the solar system and describes the main features that we observe: the rocky planets orbit more closely to the Sun and gas giants formed and orbit beyond the ice line.
