 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!

 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.
