The Outer Planets: A Star is Born [1]
Summary: Stars form in cold, dense regions of space called molecular clouds. When the force of gravity pulling in on the cloud is greater than the strength of internal pressure pushing out, the cloud collapses into a protostar.
The ISM is the name given to the gas and dust that exists between the stars within a galaxy. Molecular clouds are perfect star-forming regions because the combination of these atoms into molecules is much more likely in very dense regions.
Our own solar system presumably formed as gravity caused the collapse of a similar large cloud of gas. The piece of cloud that formed our Solar System is known as the solar nebula.

Which did not occur during the collapse of the solar nebula? [3]
Jupiter did not become a second star in this solar system.. A solar nebula is related to the formation of our Solar System, any other nebula is just a nebula.
Since the sun is only visible from the Earth’s surface during the day, this is the only time that a solar eclipse can occur.. A solar nebula is related to the formation of our Solar System, any other nebula is just a nebula.
A cloud of interstellar gas, dust, and ices containing several generations of material collapsed to form the nebula from which the Sun and the rest of our solar system grew. This collapse may have been triggered by a nearby supernova
Formation and evolution of the Solar System [4]
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] 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.. This model, known as the nebular hypothesis, was first developed in the 18th century by Emanuel Swedenborg, Immanuel Kant, and Pierre-Simon Laplace
Since the dawn of the Space Age in the 1950s and the discovery of exoplanets in the 1990s, the model has been both challenged and refined to account for new observations.. The Solar System has evolved considerably since its initial formation
Still others, such as Earth’s Moon, may be the result of giant collisions. Collisions between bodies have occurred continually up to the present day and have been central to the evolution of the Solar System
How Was The Earth Formed? [5]
The journey from a cosmic cloud of gas to the solid, rocky planet that we inhabit was long and complex. The Earth was formed through a complex process that set the foundation for many of the properties we see around us today
The Earth is part of a group of planets that formed together, alongside the Sun, and they significantly influenced each other during their evolution. Therefore, to truly comprehend how the Earth came to be, we must understand what happened during the early stages of the entire Solar System.
The nebula’s structure is sustained through hydrostatic equilibrium, that is, a balance between two opposing forces acting within it: the gaseous pressure (the gas’s tendency to spread and disperse through space and the interparticle gravitational forces that attract particles towards each other. When something disrupted this delicate equilibrium, likely a shock wave from a nearby supernova, the gravitational forces overcame the pressure, and the particles constituting the nebula were pulled towards its center of gravity in a process known as gravitational collapse.
Formation of Our Solar System [6]
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
In a similar manner, moons formed orbiting the gas giant planets. 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
The asteroids represent the rocky debris that remained.. The Earth revolves around the Sun at a distance of 150 million kilometers (93 million miles).
Our Solar System [7]
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.
So far, we have discovered thousands of planetary systems orbiting other stars in the Milky Way, with more planets being found. Most of the hundreds of billions of stars in our galaxy are thought to have planets of their own, and the Milky Way is but one of perhaps 100 billion galaxies in the universe.
It seems that we live in a universe packed with planets – a web of countless stars accompanied by families of objects, perhaps some with life of their own.Namesake. There are many planetary systems like ours in the universe, with planets orbiting a host star
The Outer Planets: How Planets Form [8]
Summary: The terrestrial planets formed close to the Sun where temperatures were well suited for rock and metal to condense. The jovian planets formed outside what is called the frost line, where temperatures were low enough for ice condensation.
It is worth noticing that the eight planets in our solar system make up two different groups; the four planets closest to the Sun make up the rocky terrestrial planets and the four planets farthest from the Sun make up the gaseous jovian planets. Why do objects that formed from the same cloud of gas have different compositions? The answer lies in where these objects formed in relation to the parent star, our Sun.
The temperature across this protoplanetary disk was not uniform. Since different materials condense at different temperatures, our solar system formed different types of planets
Solar system planets, order and formation: A guide [9]
The order of the planets in the solar system, starting nearest the sun and working outward is the following: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and then the possible Planet Nine.. The solar system extends from the sun, goes past the four inner planets, through the asteroid belt to the four gas giants and on to the disk-shaped Kuiper Belt and far beyond to the teardrop-shaped heliopause.
Beyond the heliopause lies the giant, spherical Oort Cloud, which is thought to surround the solar system.. Related: 10 incredible volcanoes in our solar system
That all changed in the late 1990s when astronomers started arguing about whether Pluto was indeed a planet. In a highly controversial decision, the International Astronomical Union ultimately decided in 2006 to designate Pluto as a “dwarf planet,” reducing the list of the solar system’s true planets to just eight.
Formation of Earth [10]
We live on Earth’s hard, rocky surface, breathe the air that surrounds the planet, drink the water that falls from the sky, and eat the food that grows in the soil. But Earth did not always exist within this expansive universe, and it was not always a hospitable haven for life.
Eventually, a mysterious occurrence—one that even the world’s foremost scientists have yet been unable to determine—created a disturbance in that dust cloud, setting forth a string of events that would lead to the formation of life as we know it. One common belief among scientists is that a distant star collapsed, creating a supernova explosion, which disrupted the dust cloud and caused it to pull together
The faster the cloud spun, the more the dust and gas became concentrated at the center, further fueling the speed of the nebula. Over time, the gravity at the center of the cloud became so intense that hydrogen atoms began to move more rapidly and violently
CHAPTER 1: THE SOLAR SYSTEM [11]
CHAPTER 1: ORIGIN OF THE PLANETS & THE SOLAR SYSTEM TODAY. Figure 1.3: The Solar System consists of the Sun, nine planets, 61 moons and a multitude of asteroids, comets and meteoroids.
The planets generally revolve in the same direction around the sun and within the plane of the ecliptic except for Pluto, which is tilted at 17o to the ecliptic.. Most of the moons revolve around the planets in the same direction as the planets revolve around the sun.
The rotations of planets, moons and other bodies are inherited from the rotation of the ancient gas cloud from which they formed.. Closest to the sun and consist of Mercury, Venus, Earth and Mars.
Chapter 15, Chapter Review [12]
Our solar system is an orderly place, making it unlikely that the planets were simply captured by the Sun. The overall organization points toward formation as the product of an ancient, one-time event, 4.6 billion years ago
In the nebular theory of the formation of the solar system, a large cloud of dust and gasthe solar nebulabegan to collapse under its own gravity. As it did so, it began to spin faster, to conserve angular momentum, eventually forming a disk
The nebular theory is an example of an evolutionary theory, in which the properties of the solar system evolved smoothly into their present state. In a catastrophic theory, changes occur abruptly, as the result of accident or chance.
Solar system – Origin, Planets, Formation [13]
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
Even after this breakthrough, many years elapsed while scientists struggled with applications of Newton’s laws to explain the apparent motions of planets, moons, comets, and asteroids. In 1734 Swedish philosopher Emanuel Swedenborg proposed a model for the solar system’s origin in which a shell of material around the Sun broke into small pieces that formed the planets
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 moving and colliding, at which point chemical forces kept them bonded together

Billions of years ago, circumstances were just right for Earth and the other planets in our Solar System to form.. The Solar System that we live in consists of a medium-size star (the Sun) with eight planets orbiting it
They are smaller and composed mainly of metals and rocks. The four outer planets — Jupiter, Saturn, Uranus, and Neptune — are larger and composed mostly of gases.
14.3 Formation of the Solar System – Astronomy 2e [15]
– Describe the motion, chemical, and age constraints that must be met by any theory of solar system formation. – Summarize the physical and chemical changes during the solar nebula stage of solar system formation
– Describe the main events of the further evolution of the solar system. As we have seen, the comets, asteroids, and meteorites are surviving remnants from the processes that formed the solar system
We are now ready to put together the information from all these objects to discuss what is known about the origin of the solar system.. There are certain basic properties of the planetary system that any theory of its formation must explain
