Our Sun
The Sun is a Yellow Dwarf star. The Romans called the Sun "Sol". This alternate name is where we get the term "Solar System" which literally means system of the Sun. The Sun is so big that is it were hollow more than 1 million Earths would fit inside it. The Sun is by far the most massive body in our Solar System. Te Sun accounts for 99.8% of the total mass of all the objects in the Solar System (planets, moons, asteroids etc.). The sun is Plasma; it is not a solid, nor is it gas. The sun is composed primarily of Hydrogen and Helium. In the core of the Sun, a process called nuclear fusion takes place. This process converts hydrogen into helium giving of light and heat. The Sun is believed to be roughly 4.57 billion years old.
The Suns averages a distance of 92,995,807.3 miles from the earth. This is called an Astronomical Unit (1AU). Light traveling from the Sun to the Earth travels at the speed of light which is 180,000 miles per second as all light does. At that speed it still takes 8 minutes for the light of the Sun to reach earth.
