Our solar system is over 4.5 billion years old and it is one of several billion solar systems in the Milky Way Galaxy. The scientific theory of how the solar system was created was when a cloud of gas and dust was disturbed by an outside force. The cloud then compressed and the particles began to stick together by forming larger objects (the planets) and the temperature and pressure rose and a nuclear fusion began and created the sun. All of the coal, oil, gas, and wood on Earth would only keep the Sun burning for a few days. The average size of a star is about 150,000 times bigger than Earth. In the Centaurus constellation is a star named Lucy. It is a huge diamond floating in space. It weighs 10 billion trillion trillion carats and is about the size of the moon. Below is a picture of the Milky Way Galaxy.
