Down: 1) HIGHEST path, rise and set at most extreme north of due east.4) Sun rises precisely due east and sets precisely due west. 5) Variation of Earth-Sun distance is small-about 3%; this small variation is overwhelmed by the effects of axis tilt 6) Depend on how earths axis affects the directness of sunlight10) Can be partial, total, or annular. Across: 2) The moon rotates exactly once with each orbit. This is why only one side is visible from earth.3) We can see over 2000 stars and Milky Way with our naked eyes, and each position in the sky belongs to one of 88 constellations. We can specify the position of an object in the horizon and it's direction along the horizon.7) Can only occur at new moon.8) Position north or south of the equator 9) It must be a full moon (for lunar eclipse) or a new moon (for a solar eclipse) AND the moon must be at or near one of two points in its orbit where it crosses the ecliptic plane (it's nodes)11) your latitude 26N12) Position east or west of prime meridian (runs through Greenwich, England) 13) Your location determines which constellations are hidden by Earth. Time of the year determines the location of the sun and stars in the sky.14) LOWEST path, rise and set at most extreme south of due east.15) Lunar phases are a consequence of the Moons 27.3-day orbit around earth. It's appearance to us is determined by the relative positions of the sun, moon, and earth.16) Changes directness of sunlight during the year17) Planets usually move slightly eastward forward from night to night relative to the stars. But sometimes they go westward relative to the stars for a few weeks: apparent retrograde motion.
