Lunar phases

5. action of rotating around an axis or center.
8. Crescent,The phase after the last quarter, where only a small part of the moon is illuminated and continues to decrease.
9. partially shaded outer region of the shadow cast by an opaque object.
11. shape of the visible part of the moon when more than half full but not completely full.
12. fully shaded inner region of a shadow cast by an opaque object, especially the area on the earth or moon experiencing the total phase of an eclipse.
14. curved path of a celestial object or spacecraft around a star, planet, or moon.
16. straight-line configuration of three celestial bodies in a gravitational system.
17. Quarter,The phase where half of the moon is illuminated, but the opposite half compared to the first quarter.
18. Eclipse,An eclipse in which the moon appears darkened as it passes into the Earth's shadow.
20. oscillation of the moon that allows observers to see slightly more than half of its surface over time.
22. distinct period or stage in a process of change, in this context, the different appearances of the moon.
24. Month,The time it takes for the moon to complete one orbit around the Earth relative to the stars (about 27.3 days).
25. event where one celestial body moves into the shadow of another celestial body.
27. periodic rise and fall of the sea level under the gravitational pull of the moon.
28. point in the orbit of the moon or a satellite at which it is nearest to the Earth.

1. lighting up of an object, in this context, the moon being lit by the sun.
2. Eclipse,An eclipse in which the sun is obscured by the moon.
3. Gibbous,The phase following the full moon, where the illumination starts to decrease.
4. Crescent,The phase following the new moon, where a small part of the moon becomes visible and increases in size.
6. Relating to the moon.
7. Quarter,The phase where half of the moon is illuminated and visible from Earth.
8. Gibbous,The phase after the first quarter, where more than half of the moon is illuminated and continues to grow.
10. Pull The force by which a planet or other body draws objects toward its center.
13. movement of one object around a center or another object, such as the moon around the Earth.
15. Moon,The phase when the entire face of the moon is illuminated and visible from Earth.
16. Month,The period of time it takes for the moon to return to the same phase (about 29.5 days).
19. dividing line between the illuminated and dark parts of the moon.
21. point in the orbit of the moon or a satellite at which it is furthest from the Earth.
23. shape of the visible part of the moon when less than half full.
26. Moon The phase of the moon when it is in conjunction with the sun and invisible from Earth.
