The Our Millenary

UniverseBy Chiara R.

… The Universe was formed by a big

explosion “The Big Bang”

The birh of our sistem Started

about 5 billion years ago…

From a nebula

It was composed by helium and

hydrogen, and suddenly ( maybe for a

supernova’s collision’s wave ) , It became a

big vortex, whit an hot and a denses nucleus

…And with the continuous collisons

between dust’s granules, the planets

were formed

This is our sistem today… It’s formed by the

Sun, Mercury, Venus, Earth,Mars, Jupiter, S

aturn,Uranus, Neptune and Pluto

This is the sun, the our

star: It’s the principal

source of energy. Whitin

there are continuous fusion

between Hidrogen for the

production of Helium.
