Solar System Formation

How Did The Solar System Form?

(Last Updated On: October 8, 2022)

Hello Kids! How did the solar system form? Many times, this question might have come to your mind. The solar system is a pretty busy place. It is got all kinds of planets, moons, asteroids, and comets zipping around the Sun. But how did this busy stellar neighbourhood come to be? Let’s find out how our solar system formed and how it came to be the busy place it is today. A Transcript of the video is added for helping the kids who have difficulty watching the video due to low internet speed.

How Did The Solar System Form?

Transcript – For Educational Purpose

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 because the shockwave of a nearby exploding star caused it to compress.

When it collapsed, it fell in on itself, creating a disk of material surrounding it.

Finally, the pressure caused by the material was so great that hydrogen atoms began to fuse into helium, releasing a tremendous amount of energy. Our Sun was born!

Even though the Sun gobbled up more than 99% of all the stuff in this disk, there was still some material left over.

Bits of this material clumped together because of gravity. Big objects collided with bigger objects, forming still bigger objects. Finally, some of these objects became big enough to be spheres—these spheres became planets and dwarf planets.

Rocky planets, like Earth, formed near the Sun, because icy and gaseous material couldn’t survive close to all that heat.

Gas and icy stuff collected further away, creating the gas and ice giants.

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. These icy bits haven’t changed much at all since the solar system’s formation.

In fact, it is the study of asteroids and comets that allows scientists to piece together this whole long story.
