1. Members of the Solar SystemBy: Rio Anne Mao

2. Solar System The solar system is made up of the sun, its planets, asteroids, meteoroids, and comets. Each of these bodies are held to each other by the force of gravity. 3. Sun A star that is the basis of the solar system and that sustains life on Earth, being the source of heat and light. It is about 865,000 miles in diameter. Its mass is almost 700 times the total mass of all the bodies in the solar system and 332,000 times that of the earth. 4. Planets Mercury Venus Earth Mars Jupiter Saturn Uranus Neptune 5. Mercury the nearest planet to the sun 36 million miles (58 million km) from the sun takes 88 days for Mercury to orbit the Sun 3,000 miles or 4,800 km diameter 59 days rotation of axis 800 degrees Fahrenheit or 450 degrees Celsius temperature 6. Mercury 7. Venus second planet from the sun 67 million miles or 107 million km from the sun 225 days to orbit around the sun 243 days rotation of axis The cloud layer holds in the heat and keeps the planet much hotter than the earth. 8. Venus 9. Earth the third planet from the sun 93 million miles from the sun 7,926 miles or 12,760 kilometers diameter surrounded by a band of gases called the atmosphere which is mostly nitrogen and oxygen. 24 hours or 1 day axis rotation 365 1/4 days revolution 10. Earth 11. Mars fourth planet from the sun 4,200 miles or 6,800 km in diameter and just over half the diameter of the earth has a very thin atmosphere made up of carbon dioxide, with some nitrogen and argon red in appearance due to oxides in its crust 80 degrees Fahrenheit or 27 degrees Celsius temperature 12. 141 million miles 228 million kilometers from the sun orbits the sun in 687 days 24 hours or 1 day rotation hot spots under the crust 13. Mars 14. Jupiter fifth planet from the sun and largest planet of the solar system 484 million miles or 778 million kilometers from the sun orbits the sun every 12 years Its mass is 318 times that of the earth and about 2 1/2 times the mass of all other planets combined. 15. The atmosphere of Jupiter is made up mostly of hydrogen, helium, methane, and ammonia Jupiter has no solid rock surface 10 hours axis rotation 16. Jupiter 17. Saturn sixth planet from the sun and second largest planet 886 million miles or 1.43 billion kilometers from the sun 29 1/2 years to orbit or revolve around the sun covered with a thick atmosphere made up of hydrogen and helium 18. Saturn 19. Uranus seventh planet from the sun 1.78 billion miles or 2.87 billion kilometers from the sun orbits the sun every 84 years 32,000 miles or 47,000 kilometers diameter weight is about 15 times that of the earth 20. has a thick atmosphere of hydrogen, helium, and methane has a thick atmosphere of hydrogen, helium, and methane 18 hours axis rotation 330 degrees Fahrenheit or -200 degrees Celsius temperature has 11 rings 21. Uranus 22. Neptune eighth and currently the last planet of solar system 3 billion miles or 4.5 billion kilometers from the sun orbits the sun about 165 years 30,700 miles or 49,000 kilometers diameter Its mass is about 17 times the earth's mass 23. It is much like Uranus as it has a thick atmosphere of hydrogen, helium, methane, and ammonia and a rapid period of rotation atmosphere has zones like Jupiter's and giant storm systems that look like dark spots on its surface has a ring system made up of three bands. 24. Neptune 25. Asteroids small, airless rocky world revolving around the sun Too small to be called planets the mass of all the asteroids is the mass of all the asteroids is less than that of Earth's moon. Most asteroids lie in a vast ring between the orbits of Most asteroids lie in a vast ring between the orbits of Mars and Jupiter 26. Meteoroids small bodies that travel through space smaller than asteroids and just a size of a pebble Most meteoroids come from asteroids that are broken apart by impacts with other asteroids 27. Breaking News! 28. Comets is an icy body that releases gas or dust contain dust, ice, carbon dioxide, ammonia, methane and more As a comet gets closer to the sun, the ice on the surface of the nucleus begins turning into gas, forming a cloud known as the coma. Radiation from the sun pushes dust particles away from the coma, forming a dust tail, while charged particles from the sun convert some of the comet's gases into ions, forming an ion tail. 29.
