objectively.

V -

Variable Star A star whose brightness varies over time due to either inherent properties of the star or something

eclipsing or obscuring the brightness of the star.

W -

Waning Moon The period of the moon's cycle between full and new, when its illuminated portion is decreasing.

Waxing Moon The period of the moon's cycle between new and full, when its illuminated portion is increasing.

Z -

Zenith The point on the Celestial Sphere directly above the observer.

Zodiac The zodiac is the portion of the Celestial Sphere that lies within 8 degrees on either side of the

Ecliptic. The apparent paths of the Sun, the Moon, and the planets, with the exception of some

portions of the path of Pluto, lie within this band. Twelve divisions, or signs, each 30 degrees in

width, comprise the zodiac. These signs coincided with the zodiacal constellations about 2,000 years

ago. Because of the Precession of the Earth's axis, the Vernal Equinox has moved westward by

about 30 degrees since that time; the signs have moved with it and thus no longer coincide with the

constellations.
