A last quarter moon looks half-illuminated. It rises around midnight, appears at its highest in the sky at dawn, and sets around noon.
Last quarter moon comes about three weeks after new moon. Now, as seen from above, the moon in its orbit around Earth is at right angles to a line between the Earth and sun. The moon is now three-quarters of the way around in its orbit of Earth, as measured from one new moon to the next.
After this, the moon will begin edging noticeably closer to the sun again on the sky’s dome. Fewer people notice the moon during the day from about last quarter on, because the sun’s glare begins to dominate the moon.
A last quarter moon can be used as a guidepost to Earth’s direction of motion in orbit around the sun. In other words, when you look at a last quarter moon high in the predawn sky, you’re gazing out approximately along the path of Earth’s orbit, in a forward direction. The moon is moving in orbit around the sun with the Earth. But, if we could somehow anchor the moon in space . . . tie it down, keep it still . . . Earth’s orbital speed of 18 miles per second would carry us across the space between us and the moon in only a few hours.
As the moon orbits Earth, it changes phase in an orderly way. Follow these links to understand the various phases of the moon.

this website rocks when i type in new moon all the other websites think its the movie but you actually have a brain and know what i say and what i mean when i say new moon[bye the way i really really want to see that movie!!!!!!!!!!!!!!!]

Well, actually most people probably are talking about the movie because I think the movie is a bit more popular than an actual moon. Just saying… :D

I was in prison a few years ago. Every night we got to go outside to smoke once an hour. I started watching the moon. I had never realized that the moon doesn’t follow the same kind of pattern that the sun follows. One night the moon might be in the East a couple of nights later it might be in the south. It would move from hour to hour but not like the sun. The moon is way more unpredictable than the sun!! It made me a moon lover.
Thanks bullwinkle … we are moon lovers here at EarthSky, too.
Pleez dont find this offensive Bullwinkle, but y wer u in prison???
And THANK U Earth Science pple! My retarded teacher spent ovr 2 wks trying 2 teach me this OVER n OVER agn, but i nevr got it. I read ur quick passage, n i get it now! I feel sooooo acomplished:D

I rarely can see the moon during the day
I am a fan of watching the moon as well. Is it just me or does it become more egg shaped as the month moves on? Can you explain this to me?
