-It is unusual NOT to have a clear night sky in southern Arizona, particularly during the summer months, which makes this area one of the best places in the world for astronomy
-The Moon is Earth's sole natural satellite and nearest large celestial body
-It is a spherical rocky body, probably with a small metallic core, revolving around Earth in a slightly eccentric orbit at a mean distance of about 238,600 miles
-Its equatorial radius is about 1,080 miles
-The moon is the brightest and largest object in the night sky on Earth
-It's responsible for tides and helps moderate Earth's wobble on its axis, which contributes to a stable climate
-The moon's rotation is locked to Earth's rotation by gravitational pull, so the same side of the moon always faces Earth ... this means that a lunar day is 29.5 Earth days long, which is the same length as a lunar month
