1. The Gas Giant Planets

2. Jupiter

3. Origin of name: From the king of the gods, Zeus or Jupiter

4. Orbit: Radius 5.20 AU [period 11.9 yr, eccentricity 0.05]. from space, its moons look like a complex miniature solar system.

5. Size: 11.2 Earth radii, 318 Earth masses More mass than all the other planets together Low density

6. Composition Mostly H 2 (70%) Dense core Surrounding layer of liquid metallic hydrogenmetallic hydrogen

7. Thin ring system

8. Magnetic field 14 times stronger than Earth's Filled with energetic charged particles emitting radio waves Deformed by the solar wind, has a long tail extending beyond the orbit of Saturn!
