How Did the Solar System Form? Here are 2 Theories of Its Formation

Bobo.id – Of galaxy Milky Way or Milky Way this, there are several Solar systemone of which, is our Solar System, the place where Earth is.

Our Solar System consists of other planets, asteroids, sun, and others.

Planets in the Solar System, such as Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune orbit the Sun in their orbits, and never move.

This is due to the strong gravitational force of the Sun, causing the celestial bodies in the Solar System to orbit the Sun.

In addition, outside our Solar System there are also dozens of moons, planets, asteroids, comets, and other meteoroids orbiting the Sun.

The Milky Way Galaxy is just one of 100 billion galaxies in the universe, lo. Then, what exactly is the meaning of the Solar System, huh?

How did this Solar System form? To find out, friends can listen to the explanation further as follows. Come on, see!

What is the Solar System?

As reported by SpaceThe solar system consists of the Sun and the celestial bodies that orbit around it, including planets, moons, asteroids, comets, and meteoroids.

Our Solar System extends from the Sun, the four inner planets, to the asteroid belt, and to the Kuiper belt.

Scientists observe that the edge of the Solar System is about 15 billion kilometers from the sun.

At the edge of the Solar System there are also heliopause (interstellar space) located in the Oort cloud is a giant round shape and surrounds the Solar System.

According to NASA, our Solar System was formed about 4.5 billion years ago, made of dense clouds of interstellar gas and dust.

The cloud collapses due to the shock wave from a nearby exploding star, this stellar explosion is called a supernova.

When this cloud collapses, it will form a loop and pull a lot of material into it.

Over time this cycle has a large core and the gases begin to bond to each other, releasing a large amount of energy.

From this process formed galaxies that form the composition of the solar system that is scattered in the galaxy.

The materials that were previously attracted, become lumpy and collide with each other, and eventually form planets, dwarf planets, and moons.

In fact, the remnants of matter that did not form planets, eventually became other celestial bodies, such as asteroids.

The cluster of asteroids converges in the area between Mars and Jupiter, called the asteroid belt.

Meanwhile, the remnants of other matter form comets, meteoroids, and small irregular moons.

This is only one theory of the formation of the solar system, in fact there are many other theories. Friends, you can listen to two other theories of the formation of the solar system, below.

Theory of the Formation of the Solar System

1. Nebula Theory Or Fog Theory

This theory was proposed by Immanuel Kant in 1755 and Pierre Simon de Laplace in 1796.

The nebula theory is a theory that states that stars and planets are formed from molecular clouds, and form their own gravity.

The molecular cloud is composed of hydrogen and helium gases produced from the Big Bang.

Due to the force of gravity, the explosive particles bond and collide, to form planets, stars, and other celestial bodies.

2. Theory Planetesimal

This theory was presented by Thomas C. Chamberlin and Forest R. Moulton in 1905. According to their research, this solar system formed simultaneously.

Initially, a Sun was not called the Sun, until there was another star that was close enough to attract the material.

That material also formed the planets that exist today. However, this theory is weak, because the formation of a solar system like this is rare.

Moreover, upon further investigation, the material released from the star turns out to be instantly lost in space.

Well, that’s the understanding of the Solar System and the theories of its formation according to scientists.
