Werewolves love to howl at a full moon. The moon is our planet’s satellite, and it rotates around the earth and reflects light from the sun. Also, “to moon” means to show your rear. The moon is out! Giggle giggle.
The earth has just one moon, but the word moon can mean any natural satellite of any planet. Astronomers have discovered many moons — there are more than 160 in our solar system alone. Poets have been fascinated by the moon for a long time, and "to moon" also means "to act in a dreamy or aimless way." Our months are marked by changes in the moon's phase, and the Proto-Indo-European root means both "moon" and "month."
