  • Hey friends! Are you wondering where I am?

  • Well, I am in space but hey, I have traveled 4.6 billion years back in time,..

  • ..exactly when our Solar System was formed!

  • Well, since we don't have that much time..

  • ..let me fast forward the process and tell you about the formation of the solar system.

  • Zoom in!

  • It is believed that our Solar System was formed..

  • ..when a cloud of dust and gas was disturbed by an explosion of a nearby star called the Supernova.

  • The star exploded with a Bang and its effect traveled in waves all around.

  • These waves squeezed the cloud of dust and gas resulting in its collapse.

  • All the little pieces of matter that started out running away from each other..

  • ..got pulled back together by gravity.

  • Soon the cloud began spinning at a tremendous speed.

  • And there it was, a beautiful Solar Nebula in the making.

  • Just for some extra information, a Solar Nebula is a large cloud of gas and dust..

  • ..from which the sun, planets, and other solar system bodies..

  • ..like asteroids, meteors and moons were formed.

  • Okay, so let's now continue from where we left off!

  • When the spinning slowed down, the centre of the Solar Nebula became hotter and denser,..

  • ..which was surrounded by a disc of gas and dust that was cool at the edges.

  • At the heart of the Nebula, there was a ball of Hydrogen gas..

  • ..who's pressure and temperature became quite huge and the particles began to fuse together.

  • There it was, a new, powerful star coming into being..

  • ..Yes, that was our Sun, shining like a fiery ball!

  • There were infinite number of particles that began to stick together and form clumps.

  • Some clumps got bigger and bigger, forming planets and moons.

  • Ahaan, so now you know how the planets were born, isn't it?

  • It is also believed that since the centre of the Solar Nebula was hot,..

  • ..like Mercury, Venus, Earth, Mars and Jupiter.

  • The rest of the cold planets like Saturn, Neptune, Uranus, etc, were formed at the edges.

  • Did you know that Sun takes up 99% of the Solar System's mass?

  • This means that we are technically living inside the atmosphere of the Sun.

  • The rocks that belong to Mars have been found on Earth.

  • And guess what, we didn't bring them here.

  • Does that make you raise your eyebrows, haan?

  • Time for me to go back to my Earth!

  • Tune in next time for more fun facts.

  • This is me Zooming out!
