What are the theories for the origin of the Solar System? Any theory about how the Solar System came to be has to account for certain, rather tricky facts. We know that the Sun sits at the centre of the Solar System with the planets in orbit around it, but these throws up five major problems:
2 days ago· 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. At some point, the cloud collapsed—possibly
Describe the characteristics of planets that are used to create formation models of the solar system; Today, some 4.5 billion years after its origin, the solar system is—thank goodness—a much less violent place. As we will see, however,
Beginning in the 16th century, Western scientists began to make careful observations about the sun and the planets. This data provided evidence for these scientists to test their ideas about
The most widely accepted model of planetary formation is known as the nebular hypothesis.This model posits that, 4.6 billion years ago, the Solar System was formed by the gravitational collapse of a giant molecular cloud spanning several light-years.Many stars, including the Sun, were formed within this collapsing cloud.The gas that formed the Solar System was slightly more
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.
Oct 29, 2024· Solar nebula, gaseous cloud from which, in the so-called nebular hypothesis of the origin of the solar system, the Sun and planets formed by condensation. Swedish philosopher Emanuel Swedenborg in 1734 proposed that the planets formed out of a nebular crust that had surrounded the Sun and then
Rotation of the Solar Nebula We can use the concept of angular momentum to trace the evolution of the collapsing solar nebula. The angular momentum of an object is proportional to the square of its size (diameter) divided by its period of rotation (D 2 P) (D 2 P).If angular momentum is conserved, then any change in the size of a nebula must be compensated for by a proportional
The ability of stars to make big atoms from small ones is key to understanding the history of our solar system and our planet. Planet Earth is made of a wide variety of chemical elements, both lightweight and heavy. All of these elements must have been present in the nebula, in order for them to be included in Earth''s "starting mixture."
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.
Figure 1a. 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).
Jan 29, 2020· As our understanding of our place in the galaxy has grown, we have re-evaluated the question of our beginnings, but in order to identify the true origin of the solar system, we must first identify the conditions that such a theory would have to meet.
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 and dust called a nebula. Nebulae are some of the most beautiful objects that have
Origin of the Solar System: The basic premise in the understanding of our origins, and the properties of all the planets we have studied this term, is that natural forces created and shaped the Solar System. And that there is a continuity to that

As we will see, however, some planetesimals have continued to interact and collide, and their fragments move about the solar
Introduction. The planetary system we call home is located in an outer spiral arm of the Milky Way galaxy. Our solar system consists of our star, the Sun, and everything bound to it by gravity – the planets Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune; dwarf planets such as Pluto; dozens of moons; and millions of asteroids, comets, and meteoroids.
Aug 22, 2024· 19.2: Origin of the Solar System—The Nebular Hypothesis Our solar system formed as 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
Origin of the Solar System We explore theories of the origin of the solar system, including the Sun, its entourage of planets and their moons, asteroids, and comets. We examine the evidence that the Sun and planets formed about 4.6 billion years ago, having condensed from an interstellar cloud of gas and
Western scientists have developed several different theories to explain the origins of our solar system. Many different scientists from different subject areas have contributed to the present theory. Ideas about the origin of the solar system have changed based on new data that has been gathered. There are still many questions to be answered.
Sep 28, 2019· Origin of the solar system hypotheses - Download as a PDF or view online for free. The document discusses the Nebular Hypothesis of La Place, which proposes that the solar system formed from a rotating cloud or nebula of dust and gas. It states that as the nebula collapsed due to gravitational forces, the central mass formed the sun and the
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. [ 4 ]
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.
Using data gathered and ideas developed over the last four centuries, today''s scientists have developed the current theory about the beginnings of the sun and planets. This theory explains that our solar system began as a spinning cloud of gas and dust about 4.5 billion years ago.
Table 17.1: Mass of members of the solar system. Note that the Sun is by far the most massive member of the solar system. Most of the material of the planets in the solar system is actually concentrated in the largest one, Jupiter, which is more massive than all the rest of the planets combined.Astronomers were able to determine the masses of the planets centuries ago using
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
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 other small Solar System bodies formed.
