3. Planets of the Solar System Planets Distance from Sun (millions) Number of Moons Year Length Mercury 69.7 km. 0 88 days Venus 109.0 km. 0 225 days Earth 152.1 km. 1 365 days Mars 249.1 km. 2 687 days Jupiter 815.7 km 16 12 years Saturn 1,507.0 km. 18 30 years Uranus 3,004.0 km. 15 84 years Neptune 4,537.0 km. 8 165 years Pluto 7,375.0 km. 1 248 years Math Connection

4. Inner and Outer Planets Location of Planets Inner Planets Planets Close to the Sun Mercury Venus Earth Mars Outer Planets Planets Far from the Sun Jupiter Saturn Uranus Neptune Pluto The farther the planet is from the sun the longer it takes to orbit the sun

5. Space Exploration your leader? Take me to your leader NASA Link Using the link, can you find a way NASA uses measurement?

6. The Moon, Earth’s Satellite  384,00 kilometers from the Earth  Reflects light from the sun  Revolves around the Earth  Has been visited by astronauts astronauts  Made of rock If a space craft travels at 38,600 km. an hour, about how long would it take to reach the moon? Math Connection

7. Space Probes Space probes are sent into space to gather information and pictures about other planets and our solar system. In 1976 NASA sent 2 Viking spacecraft to photograph and gather data about Mars. Robots called Pathfinder and Sojourner landed on Mars in 1997. Today the Hubble space telescope is traveling through our solar system sending information back to Earth. Math Connection How many years passed between the Viking landing and the Pathfinder landing on Mars?

8. How much do you weigh? Return to previous slide

9. Would you like to be an Astronaut? Astronauts study our solar system. They do experiments in space to see if the results are different from Earth. The U.S.A. has recently destroyed a comet in space. This will help to find out what comets are made of. Connect to this movie to learn more. Astronauts study our solar system.

10. Phases of the Moon Occurs 14 days after new moon The lit part of the moon is not always visible from earth The moon reflects light from the sun. A new moon occurs every 28 days

11. Interpreting a Graph Gravity is the force of attraction between two objects. If you weigh 80 pounds on Earth, how much will you weigh on Jupiter? Refer to the graph on Weight and Gravity. Does Jupiter have more or less gravitational pull than Mars? Which planet would you weigh about the same as Earth ???? Click ? To view graph

12. The Sun is a Star  The sun is made of hot gases.  The sun is the closest star.  The planets revolve around the sun.  The Earth gets light and heat from the sun.  The sun is 4.5 billion years old.

13. Asteroids and Meteoroids  Asteroids are crater covered rocks that orbit the sun  The Asteroid Belt is located between Mars and Jupiter  Asteroids measure from 2.5 cm. to 1,023 km.  Meteoroids are asteroids caught by Earth’s gravity  A meteoroid that burns up in the atmosphere is called a meteor, or “shooting star”  A meteoroid that falls to Earth without burning up is a meteorite

14. Comets  A comet is a “dirty snowball” that orbits the sun.  A comet has a nucleus (center), a coma (head), and a tail that always faces away from the sun.  Famous comets are Hale-Bopp, Halley, Hyakutake, and Shoemaker-Levy 9.  Particles in the tail may cause a meteor shower on Earth if it passes through the tail.

15. Math Activity How far are the planets from the sun?  Work with a partner.  Create a solar system showing each planet’s distance from the sun to scale.  Refer to Planets of the Solar System chart.  Using the outside hallway, mark the distance of each planet from the sun with a piece of tape and name of planet. The sun is at the end of the hall.  Use a scale of 1 cm=1,000,000 km.  Be creative to show your solar system.
