2.  The Sun is known as a G2V star. It is the largest star located in the CENTER of our Solar System.  Believe it or not the sun is not a perfect sphere. Many ridges are located on the Sun’s outer core.  Temperature = Around 10,000°F at the surface and at the core it rises to about 27,000,000°F!!  The Sun has no moons because it is a star.  A full day rotation is 26.8 days.  The sun does not have a full year rotation.  The diameter of the Sun is 1,390,000 KM

4.  The sun is made up of carbon, nitrogen, and oxygen  makes up 1.5% of the Sun.  The other 0.5% is made up of neon, iron, silicon, magnesium, and sulfur.  The sun shines by burning off Hydrogen.

5.  99.86 of the Solar System is the Sun.  Light from the Sun takes approximately 8 minutes to reach Earth!  The Sun generates Solar Wind.  One millions Earths can fit in the Sun!

6.  Every second the Sun loses 5 millions tons of material!  If the Sun were to stop producing energy today, it would take 50 million years to fully effect Earth.  Based on the average life of a G2 star the present age of the Sun is estimated to be 4.6 billion years old. (Half way through its lifetime.
