The Sun
The Sun contains more than 99.8% of all matter in the Solar System. In fact, "almost everything" in the Solar System is in the Sun. It exerts a strong gravitational pull on planets and spins them around. Along with asteroids, meteoroids, comets, and dust, they form the Solar System.
74% of solar matter is Hydrogen (H), another 24% is Helium (He) and the remaining 2% is distributed among various chemical elements, among which are Oxygen (O), Iron (Fe) and Nickel. (Neither). These gases have a convective motion that transports heat and energy outward. This dynamo effect generates a powerful magnetic field
