5. Satellite: a celestial body orbiting the earth or another planet
Earth is a satellite of the
Sun
The moon is a satellite of the
Earth
Why do the distance between the sun and earth change?
Shape of the orbit not a perfect circle
Gravitational pull changes due to distance

of the moon?
The moon's

Earth, moon, and Sun

10. 27.3 days How long does it take for the moon to revolve around Earth ?
One complete orbit of the moon around
The Earth takes?
ESRTs p15

11. One complete cycle the moon’s phases takes
29.5 days
Explain why there is a 2.5 day difference
Because you need to go back to the first phase that takes another 2.5 days

12. 27.3 days How long does it take for the moon to revolve around Earth ?
One complete orbit of the moon around
The Earth takes?
ESRTs p15

13. What phenomenon
does this explain?
We only ever see one
side of the moon.

14. Why does the moon
rise later each day?
because as the Earth
rotates, the moon
revolves
