Our
solar system, lies about 26,000 light years from the center of our galaxy the
Milkyway, or around 2/3rd the way out.

6
billion years ago, an ancient star exploded littering space with its swirling
clouds, with materials what it had made during its life time and the heavier
materials it created as it died. They
are called NEBULAE. And they are very
beautiful and in every case they are different.
And in ours it contained Nitrogen and oxygen and all the stuff needed to
build a world like ours.

Then
the force of gravity started pulling it all together and the heavy engineering
that produces planets began. Vast spirals of dust began to form. At the center of one of these, a rocky planet
called earth started to take shape, built of star dust. First for 100 million years it grew into a
giant ball sweeping all the millions of tonnes of celestial debris. This is where the earth came from.
And
then 93 million miles away, in a part of the giant nebulae the temperature and
pressure of hydrogen gas had become so great that the atoms were beginning to
dance. A new star, our sun was coming to life.
As
the sun ignited it gave a huge blast of solar flare and radio active dust and
energy. This blew all the remaining gas and dust that was remaining, out of the
solar system, which is why everything is so nice and orderly today.
In
the outer reaches of the solar system, we have the huge gas planets, Jupiter,
Saturn, Uranus and Neptune. And in the inner, we have dense planets mercury,
Venus, mars and of course our earth.
