The Moon Goes Visiting, Dec. 29, 2013
Wednesday–Sunday, Dec. 25–29, 10:08–10:14 p.m. EST. Over the next five mornings, just before dawn, the Moon will pass by two planets and a bright star. It will be just below Saturn on Dec. 29.
East and west in the sky are the reverse of east and west on Earth maps because we are looking up rather than looking down. Notice how the Moon’s crescent shrinks over the five mornings, and how the stars and planets rise 4 minutes earlier each morning.
