THE GALAXY

Our earth is a planet among groups of other planets of which all rotate round the Sun. its diameter is twelve thousand seven hundred and fifty (12,750) kilometer and it has one hundred and fifty million (150,000,000) kilometer distance from the Sun. In this limit, presently it is only nine planets that were known. The families of the Sun and its planets form the solar system or the moon system. In this system the Sun has the commandment of complete and organized movement of the planets following it and with different speeds and in different orbits which rotate round it. The orbit is a line which every planet follows in rotating round the Sun, or in a better expression, it is a journey of which every mass traversed round another mass.

The illumination and the thermal of the planets is our system that derived its fountain from the Sun. the Sun is more than one million (1,000,000) greater than our earth.

The system of our Sun is the most smallest part of the galaxies, it is milky way with the speed of eight hundred thousand (800,000) kilometer per hour, every two hundred and thirty million (230,000,000) years it rotate one time round the center of this galaxies. The distance between the systems of the Sun, from the Sun to the center of the galaxy is twenty eight thousand (28,000) years journey by light. The galaxy from hundreds of billion planets while the Sun is one of this hundreds of billion planets of our galaxy which is counted as green and pink planets, the Milky Way galaxies is the most beautiful and the most luminous galaxies of the world.

This great galaxy compare to billion of other galaxy is just one small nebula that is full of planet and the combination of these galaxies which in terms of science is known as meta-galaxy that form this world of ours.

In order for you to have the full picture of this world, it is enough for you to know the number of the galaxies in the shore less surface of creation which is more than the entire sands of the entire seacoast of the whole world.[1]
