1. What are the Outer planets? The four planets farthest from the sun are known as the outer planets. Jupiter, Saturn, Uranus, and Neptune

2. Jupiter

3. Most massive planet Composed mostly of gases  hydrogen and helium Thick atmosphere Great Red Spot – a storm larger than Earth 63 moons Jupiter is about 2 ½ times greater than that of all the other planets

4. Jupiter has many moons. Galileo was the first person to see the four largest moons through his telescope in 1610. They are about the size of Earth's moon. One Example is Europa – This is the smoothest object in the solar system.

5. Jupiter’s atmosphere has a weather system called the Great Red Spot that has been raging for centuries. It is a disturbance more than three times the size of Earth.

6. Saturn

7. The sixth planet from the Sun, Saturn is also a gas giant. Like Jupiter, Saturn’s atmosphere is mostly hydrogen and helium. Spectacular orbiting rings of ice and rock The Voyager space probe explored Saturn’s rings. It showed that the particles that make up the rings range in size from tiny grains to boulders.

9. Using the chart, What is one reason people cannot live on Jupiter and Saturn? They are both too cold to live on!

10. Using the chart, What planet has more moons? Jupiter with at least 63!

11. hmmm I wonder why it says “at least” for the number of moons??

12. Uranus

13. In 1781, William Herschel discovered a seventh planet orbiting the Sun. The gas giant Uranus is the farthest planet you can see without a telescope. So cold that the methane is a liquid. Tiny drops of liquid methane form a thin cloud that covers the planet. This gives Uranus its fuzzy blue-green look.

14. Uranus -rotates on its side -Titled at about 90 degrees from the vertical No one knows for sure why Uranus has this odd tilt. Scientists think that a very large object may have collided with the planet when the solar system was still forming. This bump may have knocked Uranus onto its side.

15. Neptune

16. Smallest of the gas giants. Even so, if Neptune were hollow, it could hold about 60 Earths. Cold, blue planet (color comes from methane) Great Dark Spot Giant storm, but did not last long 13 moons Largest moon  Triton and it is covered with nitrogen ice

17. Which planet has a larger diameter? Uranus

18. How much longer is the Earth day on Uranus? One hour

20. Galileo lived from 1564 to 1642. He was a mathematician and astronomer. He agreed with Copernicus that all planets revolve around the Sun. Galileo used a telescope to observe the Sun, Moon, planets, and stars.

21. When I saw Saturn through my telescope, I was surprised. I saw what looked like a planet with handles! The “handles” were actually the brilliant ring system that orbits the planet.

23. Until 2006, Pluto was considered a ninth planet. But Pluto is different from the eight planets in several ways. Now scientists refer to Pluto as a dwarf planet. A dwarf planet is a small, ball- shaped object that revolves around the Sun.
