2. INTRODUCTION Our solar system is part of the Milky Way galaxy The solar system consists of the Sun and planets that gravitationally orbit around it The solar system is approximately 4.6 billion years old The solar system consists of four inner planets (Terrestrial Planets) Mercury, Venus, Earth, and Mars and four outer planets (Gas Giants) Jupiter, Saturn, Uranus, and Neptune

3. The Sun is the star at the center of the Solar System. Diameter: 1.4 million kilometers or 870,000 miles. Composition: 71% hydrogen, 27% helium and less than 2% of all other elements. Atmosphere: photosphere, chromosphere, and corona. Layers: core, radiation zone, and convection zone THE SUN

4. The first planet from the Sun Diameter: 4,878 kilometers Distance from Sun: 58 million kilometers (0.39 AU) Atmosphere: carbon dioxide, nitrogen, argon, oxygen, carbon monoxide, water vapor, nitric oxide MERCURY

5. The second planet from the Sun Diameter: 12,100 kilometers Distance from Sun: 107 million kilometers (0.72 AU) Atmosphere: carbon dioxide and nitrogen. VENUS

6. The third planet from the Sun Diameter: 12,715.43 kilometers Distance from Sun: 150 million kilometers (1.0 AU) Atmosphere: nitrogen and oxygen Earth is the only planet we know of to have life EARTH

7. Fourth planet from the Sun Diameter: 6,792 kilometers Distance from Sun: 228 million kilometers (1.52 AU) Atmosphere: carbon dioxide, nitrogen, argon MARS

8. Belt of asteroids located between the planets Mars and Jupiter Distance from Sun: approx. 2.8 AU Size of asteroids vary from very small to about 930 kilometers ASTEROID BELT

9. The fifth planet from the Sun Diameter: 142,984 kilometers Distance from Sun: 778 million kilometers (5.2 AU) Atmosphere: hydrogen and helium The Great Red Spot is an anticyclone storm that could fit two to three Earth sized planets JUPITER

10. The sixth planet from the Sun Diameter: 120,536 kilometers Distance from Sun: 1,429 million kilometers (9.5 AU) Atmosphere: hydrogen and helium Saturn’s rings extend from 6,630 km to 120,700 km and are about 20 meters thick SATURN

11. The seventh planet from the Sun Diameter: 51,118 kilometers Distance from Sun: 2.87 billion kilometers (19.2 AU) Atmosphere: hydrogen, helium and methane URANUS

12. The eighth planet from the Sun Diameter: 49,500 kilometers Distance from Sun: 4.5 billion kilometers (30.1 AU) Atmosphere: hydrogen and helium NEPTUNE

13. The second largest known dwarf planet in the solar system Diameter: 2,320 kilometers Distance from Sun: 5.9 billion kilometers (39.5 AU) Atmosphere: a thin layer of gases surround pluto PLUTO

14. A region in the solar system outside of the orbit of Neptune from about 30 AU to 50 AU 20 times as thick as the asteroid belt Three dwarf planets exist in the Kuiper belt Pluto, Haumea, and Makemake KUIPER BELT

15. CONCLUSION Andromeda is the close galaxy to the solar systems galaxy There are more that 140 moons in the Solar System The Sun will eventually turn into a red giant and finally a white dwarf
