  1. Planets

  2. Sun • Energy comes from Nuclear Fusion: Hydrogen atoms join together to form Helium • Three zones/layers of the Sun: • Convection Zone • Radiation Zone • Core • Features of the Sun include: • Sunspots: areas of gas that are cooler than those around it • Prominences: huge reddish loops of gas • Solar Flares: super heated gas eruptions • Solar Wind: wind from the corona as a result of a solar flare

  3. Mercury • DISTANCE FROM THE SUN : About 36,000,000 miles • DIAMETER : About 3,000 miles • DAYS TO ORBIT AROUND THE SUN : 88 Earth days • ROTATION ON ITS AXIS: 59 Earth days • ATMOSPHERE : Almost non existent-trace amounts of Hydrogen and Helium • NUMBER OF MOONS: 0 • TEMPERATURE : 810° F, -279°F *FASTEST ORBITING SPEED AROUND THE SUN: 30 mi./sec.
