Across
- 1. the movement of a planet around the Sun
- 5. the 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
- 8. an eclipse in which the sun is obscured by the moon
- 11. the time or date (twice each year) at which the sun crosses the celestial equator, when day and night are of approximately equal length (about September 22 and March 20)
- 12. the highest point in the development of something; a climax or culmination
- 14. the state or period of an eclipse when light from the eclipsed body is totally obscured
- 15. a half of the earth, usually as divided into northern and southern halves by the equator, or into western and eastern halves by an imaginary line passing through the poles
- 16. the point in the orbit of a planet, asteroid, or comet at which it is furthest from the sun
Down
- 2. Edge of sun remains visable
- 3. an eclipse in which the moon appears darkened as it passes into the earth's shadow
- 4. the point in the orbit of a planet, asteroid, or comet at which it is closest to the sun
- 6. the rotation of planet Earth around its own axis
- 7. the angle between the direction of the positive pole and the normal to the orbital plane
- 9. the time or date (twice each year) at which the sun reaches its maximum or minimum declination, marked by the longest and shortest days (about June 21 and December 22)
- 10. the angular distance of a place north or south of the earth's equator, or of a celestial object north or south of the celestial equator, usually expressed in degrees and minutes
- 13. an imaginary line drawn around the earth equally distant from both poles, dividing the earth into northern and southern hemispheres and constituting the parallel of latitude 0°
