About 15 billion years ago a huge explosion started the expansion of the universe. This explosion is known as the Big Bang. At the point of this event all of the matter and energy of space was contained at one point. The Big Bang created our universe that now consists of our own Milky Way Galaxy and many other galaxies. Also, the big bang made every planet, star, matter and energy in the universe. Some evidence to support the big bang theory is that all the galaxies are moving away from each other.

The formation and evolution of the Solar System is estimated to have begun 4.5 billion years ago. A nebula (a huge dust cloud left over from the original stars of the galaxy) started collapsing under its own gravity. Over a period of millions of years, it shrank, heating up as it contracted and compressed in the center. Then the matter around the center fell inward toward the spinning center, and flattened into a rotating disk.

As the disk got thinner and thinner, particles began to stick together and form clumps. Some clumps got bigger, as particles and small clumps stuck to them, eventually forming planets or moons . Near the center of the cloud, where planets like Earth formed, only rocky material could stand the great heat. Icy matter settled in the outer regions of the disk along with rocky material, where the gas giant planets like Jupiter formed. As the cloud continued to fall in, the center eventually got so hot that it became a star, the Sun, and blew most of the gas and dust of the new solar system outward.

The larger clumps (planetesimals) collided and combined to form planets, all of which were originally molten rock. The planets swept loose dust and gas from their orbits, and began to cool, forming atmospheres. Smaller chunks either broke up into smaller chunks or were drawn together to form asteroids and moons.

What begins in the process of solar system formation?

The formation of sun is the most important part of solar system formation. Sun is the reason for formation of rocky planets.


What is the force that caused the formation of the plants in our solar system?

Plants in our solar system, including those on Earth, formed due to the force of gravity that led to the condensation of dust and gas in the early solar system. This process eventually allowed for the formation of protoplanetary disks, which served as the birthplace of plants through processes such as accretion and differentiation.


When did scientist believe your solar system formed?

The solar system is believed to have formed about 5 billion years ago, and by the way, why do you call it YOUR solar system? Do you come from a different solar system? Because if not, then it's OUR solar system.


What events led to the formation of the solar system?

The solar system formed around 4.6 billion years ago from a rotating disk of gas and dust in space. Gravity caused the material in the disk to clump together, eventually forming the sun at the center and planets, moons, and other objects orbiting around it. This process, known as planetary accretion, led to the formation of the solar system as we know it today.


The fact that the primeval nebula was rotating slightly caused?

the material to flatten into a disk shape due to centrifugal forces. This conservation of angular momentum led to the formation of the solar system as we know it, with the Sun in the center and the planets orbiting in a plane.

What event led to the formation of our solar system, including the keyword "formation"?

The formation of our solar system was triggered by the collapse of a giant molecular cloud, leading to the creation of the Sun and its surrounding planets.


Which did not occur during the collapse of the solar nebula?

One of the events that did not occur during the collapse of the solar nebula was the formation of the first stars in the universe. Instead, the collapse of the solar nebula led to the formation of our solar system.


When did the formation of the solar system occur?

The formation of the solar system occurred around 4.6 billion years ago. The process began with the gravitational collapse of a giant molecular cloud and eventually led to the formation of the Sun, planets, and other celestial objects.

What is a piece of rock that is similar to the material that formed the planets?

Asteroids are pieces of rock that are similar in composition to the material that formed the planets in our solar system. They are remnants from the early stages of solar system formation and can provide clues about the processes that led to the formation of planets.
