| Saturn is a | gaseous planet |
| Saturn's tilt causes it to have | Seasons |
| Astronomers often call Saturn and Jupiter | Twin planets |
| Saturn is 300 degrees below zero however its center is | 20,000 degrees! |
| The stripes seen around Saturn are bands of | clouds which contain storms |
| Saturn is the only planet in the Solar System that is less dense than | water - which means it would float in water |
| Saturn has thousands of rings - they are made of | dust and ice and rocks that orbit the planet |
| What do we call Saturn's moons which herd together rings as If they were sheep | Shepherd moons |
| Two of Saturn moons are called | Pandora and Prometheus |
| Saturn's rings are on the edge are | 50 miles thick |
| Saturn takes how long to rotate on its axis once | 10 earth years |
| Saturn's fast rotation causes | strong winds and terrible storms |
| Saturn has more than | 30 moons (the second most in the Solar system behind Jupiter) |
| Saturn's biggest moon is | Titan (almost as big as Mercury) |
| Many of Saturn's moons look like irregularly shaped | rocks |
| The spacecraft trip to explore Saturn and her moons is called the | Cassini Mission |
| The spacecraft exploring Saturn will send out a probe called | Hudgens (Named after the scientist who discovered Saturn ring) |
| Probe will collect and test samples of dirt from | Titian |
| How long does it take Saturn to rotate around the sun | 30 earth years |
| Saturn is made of | Hydrogen and Helium |
| Jupiter is considered | Saturn twin |
| Why does Saturn look as if it is being squeezed? | its spinning so fast that it looks like it is being squeezed |
| Saturn is | yellowish brown |
| one year on Saturn is like | 10,950 earth days |
| 1 day on Saturn is | 10 earth hours |
| what chemical makes Uranus blue green in appreance | methane |
| why does Uranus look like a ball rolling around the sun | it is lying down |
| the planets around it have a gravitational pull that make Uranus orbit wobble | |
| Why was it so exciting to discover Uranus? | it was completely new - it was the first plane to be discovered in a long time |
| who discovered uranium? | William and Caroline Hershel they were homeschooled |
| It take Uranus to orbit the sun | 84 years |
| Neptune was discovered because | |
| what chemical gives Neptune its blue color | hydrogen, helium, methane, other gases |
| us Neptune the 8th planet from the sun explain | until it switches places with Pluto |
| It take Neptune 164 years | to revolve around the sun |
| Huge crater on Saturn's moon, Mimas, was named after the man who discovered both Uranus and Mimas | Herschel Crater |
| the Great Dark Spot | huge storm that was one visible on Neptune but not visible today |
| Eureka | I found it |
| Triton | Neptune's biggest moon |
| Cordelia and Ophelia | shepherd moons in Uranus rings |
| moons of Uranus are named after characters in the writings of | William Shakespeare and Alexander Pope - not after Roman myths and legends |

| A Year on Neptune is | 164 Earth Years |
| A Day on Uranus is | 16 Earth Hours |
| A Year on Uranus is | 84 Earth years |
| Uranus rotation is unusual because | it spins in the opposite direction compared to most planets |
| Saturn's storms are stronger than | |
| Neptune's largest moons have | Geysers on its surface that spew out chemicals |
| Similar to the asteroid belt only the objects in it are much larger and much colder | Kuiper belt |
| Objects in the Kuiper Belt look a lot like Pluto so they are called | plutinos |
| Kuiper Belt is named | after Gerard and Kuiper |
| Kuiper Belt was proved to exist in | 1992 |
| Object about 1/2 the size of Pluto was found in the Kuiper Belt called | Quaoar |
| Pluto was named for the Roman God | death |
| Discovered because astronomers thought something was pulling on Neptune | Pluto |
| Pluto has | weak gravity |
| Every 248 years Neptune and Pluto switches | places for 20 years - Pluto is the 8th and Neptune is the 9th |
| Pluto was discovered in | 1930 |
| The Hobble Space Telescope | (giant telescope floating in space) now makes it easier to study Pluto and the Kuiper Belt |
| Pluto looks like a comet's | nucleus |
| Pluto is | very cold about 390 degrees below zero |
| Pluto has a | thin atmosphere |
| Pluto rotates in the opposite direction compared to most planets the other 2 planets that do this are | Uranus and Venus |
| Pluto lies on its dike like | Uranus |
| Pluto takes | 6 Earth days to rotate on its axis |
| Pluto takes | 248 earth years to revolve around the sun |
| Charon is | Pluto's large moon |
| Sometimes Pluto and Charon are referred to as a | double planet - because they are so close in size and to each other |
