  1. Sun structure Diameter: 1.35 million Km./864,000 miles.Volume: 1.3 million x Earth.Density: ¼ that of Earth.Mass 330,000 x Earth

  2. ZONES OF THE SUN • SUN SPOTS:STORM IN THE LOWER ATMOSPHERE OF THE SUN THAT APPEAR AS DARK SPOTS ON THE SURFACE. THEY APPEAR DARK BECAUSE THEY ARE COOLER THAN THE REST OF THE SUNS SURFACE. MOVEMENT OF SUNSPOTS INDICATES THAT THE GASES IN THE SUN SPIN, OR ROTATE.

  3. PHOTOSPHERE • 6,000 C THE INNERMOST LAYER OF THE LIGHT PRODUCING PART OF THE SUN. OFTEN REFERRED TO AS THE ‘SURFACE’ OF THE SUN BECAUSE WE CAN SEE IT.ABOUT 550Km THICK (488 MILES).

  4. CHROMOSPHERE • 27,800 CBENEATH THE CORONA IN THE MIDDLE LAYEROF THE SUNS ATMOSPHERE. • SEVERAL THOUSAND Km THICK (2938 MILES).

  5. CORONA • THE OUTERMOST LAYER OF THE SUN’S ATMOSPHERE. TEMPERATURES CAN REACH 1,700,000 C.

  6. SOLAR PROMINENCE • TWISTED LOOPS OF HOT GAS THAT USUALLY ORIGINATE IN THE CHROMOSPERE. THIS IS A VIOLENT STORM ON THE SUN.

  7. INNER CORE • 15,000.000 CTHIS IS WHERE HYDROGEN ATOMS ARE FUSED INTO HELIUM ATOMS IN THE NUCLEAR FUSION REACTION.THE PROCESS IS CALLED NUCLEOSYNTHESIS.
