1. The Sun, Stars and Solar System Objects Beyond the Earth’s Atmosphere

2. What is the sun? What “state” is it in?

3. Sun Safety When studying the sun safety is very important! Write one sun safety rule: Never look at the Sun directly!

4. The Sun From the Earth The Earth revolves, or makes one revolution around the Sun in ONE YEAR.

5. The Sun as seen through a _________ with a special filter. The special filter helps prevent eye damage.

6. The Sun and Solar Flare

7. Sun Facts Makes life on our planet possible by giving us great amounts of light and heat. Contains about 98% of the mass of the entire Solar System. Is just a medium sized star (yellow dwarf). It is about 1.4 million kilometers in diameter.

8. Sun Facts It is the center of our Solar System. All the planets and other objects orbit around it. It is very gaseous, and made up mostly of hydrogen. Contains dark spots that are known as sunspots. ( These are due to temperature differences. Sunspots are cooler areas of the sun.)

9. How is the sun different than other stars?

10. Stars

11. Star Facts Stars are formed initially from gas and dust. They are made mainly of hydrogen gas. Stars are formed initially from gas and dust. They are made mainly of hydrogen gas. Stars are very hot and give off huge amounts of energy in the form of heat and light. Stars are very hot and give off huge amounts of energy in the form of heat and light. Our Sun is a medium sized star. Our Sun is a medium sized star.

12. More Star Facts Stars are very far away from Earth. The closest Star is about 23.5 trillion miles away. Stars are very far away from Earth. The closest Star is about 23.5 trillion miles away. A group of stars that form a star picture is called a ___________. The night sky has about ____ constellations. constellation 88

13. Do you know this constellation? If you guess the Scorpion or Scorpius, you’re right!

14. Swan Constellation

15. The Constellation Orion Watch the next diagram very carefully.

16. Orion Again! What does this outline possibly represent? Any ideas?

17. Orion

18. How is the solar system different than the sun?

19. How do we remember the order of our planets? My Very Energetic Mother Just Served Us Nachos!

20. Another Look at the Solar System Dwarf Planets Limitations of this Model?The DISTANCE between objects and the SIZE of the Sun and planets. There are four small inner planets There are Four LARGE outer planets Pluto Eris

21. Solar System

22. The Solar System Contains the eight planets and other smaller objects such as minor planets, comets, meteoroids and cosmic dust. The first four inner planets (Mercury, Venus, Earth, and Mars) are relatively small and resemble the Earth in composition (rocky). The next four planets (Jupiter, Saturn, Uranus, and Neptune) are much larger planets and are very gaseous in nature. Pluto is now called a minor or dwarf planet that is far from the sun.

23. The Solar System Continued All the objects in our Solar System orbit the Sun. It is so big that everything in our Solar System could fit in it many times. Many scientists believe that our Solar System is over 4.6 billion years old. All the objects in our Solar System orbit the Sun.

25. Sailing Out to Space I dream of sailing out to space, Upon a yacht of stars. With port holes all along the sides, I'd gaze amazed at Mars. With stars in front and stars behind, And planets far and near, I'd sail my yacht around the rings, Of Saturn with a cheer.
