How A Planet Forms – Explained In 3 Easy Steps

Did you know that there are at least 100 billion stars in our Milky Way Galaxy?

The world population of humans right now is about 8 billion, and this will result us into thinking that there are so much stars in the milky way that are much bigger in size and number than humans.

But then, similarly to humans, the stars also has their own story of their lives, like where they grew up, how big they are, or how many planets (For humans, their own children) they have around them.

This article is going to talk about the beginning of their stories, which is the birth of the stars.

You can learn how small rocks slowly become big fathers and mothers of the children (Planets).

The Beginning With a Cloud of Dust

Stars form in large clouds of gas and dust called molecular clouds. These clouds range from 1,000 to 10 million times the mass of the Sun.

This molecular clouds can lead the gas to be a cluster, creating high-density pockets. These clusters can collide with each other or gather up matter to strengthen their gravitational forces and their size to become sand to pebbles to rocks.

The Evolution of the Pebbles

As the collision of the stars continue, the friction happening during the event leads the material to heat up. This leads for the rocks to be a protostar, which is a baby star.

This takes about a 100,000 to 10,000,000 years to form, depending on the size it’s going to be.

Finally Into A Star

Finally, after around a million years of this sequence, the star is going to be huge like the sun or much more bigger or smaller.

And eventually after that, the rings around the star will slowly going to transform into planets like how the star did, and finally forms a family of stars and planets.
