6.     How close are the nearest stars to the Sun    as compared to the distance between the Sun and the Earth?

7.     How large is the Milky Way galaxy?

8.     How many stars are estimated to exist in this galaxy?

9.     How old is the earth compared to the universe itself?

 
Motion in the Universe

 

10.  How fast does the Earth move around the Sun? Compare that to fast things in day-to-day life.

11.  How is the Sun moving in the galaxy?

12.  How are the galaxies around the Milky Way galaxy moving from humans’ point of view?

 
Significance of the Celestial Sphere

 

13.  What important directions and coordinate systems help you find your way around the sky?

14.  Why do stars have different levels of brightness and how does one describe their brightness as compared to one another?

15.  What are constellations?

16.  What is Polaris, and what is its significance in the sky?

23.  How does the Earth rotate, and how does that relate to day and night or the seasons?

24.  How does the Earth revolve, and how does that relate to day and night or the seasons?

25.  What causes the seasons? Is it the tilt of the Earth’s axis or its changing distance from the Sun throughout the year?

 
Gravity, Free Fall, and Orbits

 

26.  What is gravity, and how much weaker does it get as you get farther from the center of a body?

27.  Are objects in orbit of the Earth still under the influence of gravity?

28.  An object in orbit falls around the Earth. What do planets, comets, and asteroids fall around?
