2. Rules for our adventure 1.We will work our hardest to learn about the key facts and figures that comprise our solar system, the Milky Way. 2.We will participate with open minds, as we journey to our destinations. 3.We will be respectful and responsible with regards to our own opinions and those of others. 4.We will keep our hands and feet inside the moving spacecraft at all times, so we do not hit any stars, planets or space dust that we may encounter.

(806F) * It has almost no atmosphere so at night all the heat escapes into space dropping the temperature to −170°C. (-274F) * Greatest range of temperatures than any other planet.

6. Similar in size to Earth. Density and internal structure of Venus are similar to Earth's. However, in many other ways, Venus is very different from Earth. Takes about 7.5 Earth months to revolve around the sun. Takes about 8 months for Venus to rotate on its axis. Venus rotates so slowly that its “day” is longer than its “year.” Rotates from east to west, the opposite direction from most other planets and moons. This type of rotation is called retrograde rotation. Atmosphere is so thick that every day is a cloudy one. Pressure of Venus's atmosphere is 90 times greater than the pressure of Earth's atmosphere. Could not breathe on Venus because its atmosphere is mostly carbon dioxide. Clouds are partly made of sulfuric acid.

7. Courtesy of www.StoryBots.com: A beautiful World, Earth song It is the only planet that has an atmosphere containing 21 percent oxygen. It is the only planet that has liquid water on its surface. It is the only planet in the solar system that has life. The Earth is the only inner planet to have one large satellite, the Moon. The Earth is fragile. Its surface is split into plates (tectonic plates) which float on a rocky mantle – the layer between the surface of the earth, its crust, and its hot liquid core.

8. Axis is tilted so Mars has seasons just as Earth does. Barren and covered with craters like the moon. Regions of Mars have giant volcanoes. No oceans or puddles of water exist. Photographs taken from space do show evidence that water flowed on Mars millions of years ago. Atmosphere of Mars is mostly carbon dioxide. Has only 1 percent the pressure of Earth's atmosphere. Astronomers have found that some water remains on Mars in the form of ice at its north pole. Mars' south pole has an ice cap made mostly of frozen carbon dioxide.

9. Largest Planet Atmosphere: Hydrogen and Helium 16 Moons – (4 Large Moons) (Ganymede, Europa, Callisto, Io ) Great Red Spot (Huge Storm) Differential Rotation: The equator spins faster than either the North or South poles, which is a trait of Jovian planets Thin ring system Day: 10 hrs Year: 12 Years Music provided by the Los Angeles Philharmonic Orchestra: Jupiter, the Bringer of Jollity

10. 2 nd Largest Planet Has 22 Moons Titan: Moon with its own Atmosphere Day: 10 hours Year: 29.5 years Music provided by the Los Angeles Philharmonic Orchestra: Saturn, the Bringer of Old Age Large ring system-ice, rock, and dust that measures some 50,000 miles across and 200 yards deep Nearly twice as far away from the Sun as Jupiter Atmosphere: Hydrogen, Helium

11. About the size of Neptune Discovered by Sir William Herschel 1781 Atmosphere: hydrogen, helium methane About 15 Moons Thin ring system Rotates on its side Rocky core Day: 18 hours Year: 84 years Most of Uranus’ moons are named after characters in Shakespearean plays Music provided by the Los Angeles Philharmonic Orchestra: Uranus, the Magician

12. A little smaller than Uranus, but similar composition Methane atmosphere Last planet seen by Voyager Rocky core 8 Moons (Triton & Nereid) The largest Triton is one of two Moons in Solar System with its own atmosphere (Titan is other) Thin ring system Once a great dark spot, that recent Hubble telescope pictures state has disappeared Day: 19 hours Year: 165 years Music provided by the Los Angeles Philharmonic Orchestra: Neptune, the Mystic

13. Pluto Discovered in 1930 “Dwarf” Planet Icy/rocky Planetoid 1 Moon-Charon (“double planet”) rotate around one another Thin atmosphere-frozen gases Space probe: New Horizon 2015 Pluto is one of many “Planetoids” Day: About 6 Earth days Year: 248 Earth Years (tilted orbit)
